Solvent properties of water (article)

Has life ever given you lemons? If so, you've no doubt followed the old adage and made lemonade - involving, of course, a lot of sugar! If you've stirred sugar into lemonade (or tea, or any other water-based drink) and watched it dissolve, then you've already seen the solvent properties of water in action. A solvent is simply a substance that can dissolve other molecules and compounds, which are known as solutes. A homogeneous mixture of solvent and solute is called a solution, and much of life’s chemistry takes place in aqueous solutions, or solutions with water as the solvent. Thanks to its ability to dissolve a wide range of solutes, water is sometimes called the "universal solvent." However, this name isn't entirely accurate, since there are some substances (such as oils) that don't dissolve well in water. Generally speaking, water is good at dissolving ions and polar molecules, but poor at dissolving nonpolar molecules. (A polar molecule is one that's neutral, or uncharged, but has an asymmetric internal distribution of charge, leading to partially positive and partially negative regions.) Water interacts differently with charged and polar substances than with nonpolar substances because of the polarity of its own molecules. Water molecules are polar, with partial positive charges on the hydrogens, a partial negative charge on the oxygen, and a bent overall structure. The unequal charge distribution in a water molecule reflects the greater electronegativity, or electr...

Acids, Bases, and Salts

The chemical compounds around us can easily be categorised as Acids, Bases and Salts. Acids, Bases and Salts are compounds which occur naturally and can also be created artificially. They are found in various substances including our food. Vinegar or acetic acid is used as a food preservative. Citrus fruits have citric acid and etc. Other than food they also have a wide variety of uses such as in various industries, manufacturing plants, processing plants, laboratories and others. In this article, we will learn about Acids, Bases, and Salts, their properties, types, uses and others in detail. The image given below shows acid and base which when reacting form salt. • Acids have a Sour flavour. • They turn Blue litmus Red. • Acid conduct electricity in their aqueous form Chemical Properties of Acid Acid has various chemical properties few of the following chemical properties of acids include, Reaction of acids with metal: When an acid reacts with a metal, it produces hydrogen gas and the corresponding salt. Metal + Acid → Salt + Hydrogen Example: When hydrochloride acid combines with zinc metal, it produces hydrogen gas and zinc chloride. Zn + 2HCl → ZnCl 2 + H 2 Reaction of acids with metal carbonate: When acids react with metal carbonates, they produce carbon dioxide gas and salts as well as water. Metal carbonate + Acid → Salt + Carbon dioxide + Water Example: When hydrochloric acid combines with sodium carbonate, it produces carbon dioxide gas, sodium chloride, and water...

Salt

salt (NaCl), sodium chloride, Properties of common salt are shown in the table. Salt is essential to the health of both people and animals. Table salt, used universally as a seasoning, is fine-grained and of high purity. To ensure that this hygroscopic (i.e., water-attracting) substance will remain free-flowing when exposed to the atmosphere, small quantities of The meat-packing, sausage-making, fish-curing, and food-processing industries use salt as a In the Get a Britannica Premium subscription and gain access to exclusive content. The habitual use of salt is intimately connected with the advance from salt thus acquired namak ḥarām, “untrue to salt” (i.e., disloyal or ungrateful). In English the term “salt of the earth” describes a person held in high esteem. Salt contributes greatly to our knowledge of the ancient highways of commerce. One of the oldest Salt Route) over which Roman salt from

Shaking Out the Facts About Salt

Potato chips, popcorn, pretzels, nuts. These popular foods all have something in common—lots of salt. Many people find a salty taste pleasant, but salt does more than simply add saltiness. It can also enhance sweetness and hide unpleasant metallic or chemical flavors, rounding out the overall balance of flavors and improving the taste of food. Flavor can also be enhanced by adding herbs, spices, and vinegars, but adding salt is a cheap and easy way to make food taste good. Unfortunately, taking too much salt has been associated with high blood pressure, which can damage the heart and blood vessels and increase the risk of a heart attack and stroke. For decades, the U.S. government and the American Heart Association have recommended consuming less salt. But reduced consumption of salt has not been shown to reduce blood pressure and has not led to a decrease in heart attack and stroke in the U.S. population. Yet current guidelines still call for limiting salt intake to stay healthy. So how much salt do we actually need to take to stay healthy? Health effects of salt Cutting back on salt can reduce blood pressure, but often, the change in blood pressure is small. According to the American Heart Association, a person who reduces salt intake from median levels (around 3,400 milligrams (mg)) to the federal recommended levels (no more than 2,300 mg) typically sees a slight drop of 1% to 2% in blood pressure, on average. Also, other factors affect blood pressure. For example, bloo...

5.1: Sugar and Salt

\( \newcommand\)). Video \(\PageIndex \] Video \(\PageIndex\): A science experiment in the kitchen shows what happens to sugar molecules when they are heated. The experiment did not disappoint! As with salt, sugar has radically different properties (both physical and chemical) than its constituent elements. This difference in properties, of constituent elements and compounds, is a central feature of chemical reactions.

Sodium

Facts You Should Know: The Periodic Table Quiz Significant uses Two of the earliest uses of metallic sodium were in the manufacture of sodium cyanide and sodium peroxide. Significant quantities were used in the manufacture of Sodium also is used as a starting material in the manufacture of sodium hydride (NaH) and sodium borohydride (NaBH 4). In addition, sodium is employed in the production of Get a Britannica Premium subscription and gain access to exclusive content. Molten sodium is an excellent heat-transfer fluid, and, because of this property, it has found use as coolant in liquid-metal fast 4) with sodium. The products are metallic Ti and NaCl. Principal compounds Sodium is highly reactive, forming a wide variety of compounds with nearly all inorganic and organic +). Compounds that contain the sodium anion, Na −, have also been synthesized. The principal commercial sodium compounds are the chloride, carbonate, and sulfate. The carbonates contain the carbonate ion (CO 3 2–). 3, is a source of 2CO 3, is widely distributed in nature, occurring as 2CO 3·H 2O, is employed extensively in photography as a constituent in developers. 2SO 4, is a white 2SO 4·10H 2O, commonly known as Glauber’s salt. 2 2O 3, is used by photographers to fix developed negatives and prints; it acts by dissolving the part of the

Sodium Chloride

Sodium Chloride Sodium chloride (chemical formula NaCl), known as table salt, rock salt, sea salt, and the mineral halite, is an ionic compound consisting of cube-shaped crystals composed of the elements sodium and chlorine. It is responsible for the saltiness of the world ’s oceans. This salt has been of importance since ancient times and has a large and diverse range of uses. One of its largest uses is as an ingredient of salt that humans use in the eating and preparing of foods. It can be prepared chemically and is obtained by mining and evaporating water from seawater and brines. Sodium chloride is colorless in its pure form. It is somewhat hygroscopic, or absorbs water from the atmosphere. The salt easily dissolves in water. Its dissolution in water is endothermic, which means it takes some heat energy away from the water. Sodium chloride melts at 1,474 °F(801 °C), boils at 2,670 °F(1,465 °C), has a density of 2.16 g/cm 3 (at 25 °C), and conducts electricity when dissolved or in the molten state. An ionic compound such as Sodium (chemical symbol Na) is an alkali metal and tends to lose an electron to form the positive sodium ion (Na +). Chlorine (chemical symbol Cl) is a nonmetal and tends to gain an electron to form the negative chloride ion (Cl -). The oppositely charged ions Na + and Cl - attract to form an + is surrounded by six anions (Cl -) and each Clis surrounded by six cations (Na +). Thus the ionic compound has a balance of oppositely charged ions and the to...
