Ethanoic acid formula

Acids An acid can be defined in several ways. The most straightforward definition is that an acid is a molecular compound that contains one or more hydrogen atoms and produces hydrogen ions \(\left( \ce\)) is the anion after the acid dissolves. Organic acids are also an important class of compounds, but will not be discussed here. Naming Oxyacids An oxyacid is an acid that consists of hydrogen, oxygen, and a third element. The third element is usually a nonmetal. a. Oxyanions with -ite ending. The name of the acid is the root of the anion followed by the suffix -ous. There is no prefix. b. Oxyanions with -ate ending. The name of the acid is the root of the anion followed by the suffix -ic. There is no prefix. Writing Formulas for Acids Like other compounds that we have studied, acids are electrically neutral. Therefore, the charge of the anion part of the formula must be exactly balanced out by the \(\ce\): Crisscross approach to writing formula for sulfuric acid.

\( \newcommand\) • • • • • • • • • • • • • • \(K_a\) is an acid dissociation constant, also known as the acid ionization constant. It describes the likelihood of the compounds and the ions to break apart from each other. As we already know, strong acids completely dissociate, whereas weak acids only partially dissociate. A big \(K_a\) value will indicate that you are dealing with a very strong acid and that it will completely dissociate into ions. A small \(K_a\) will indicate that you are working with a weak acid and that it will only partially dissociate into ions. General Guide to Solving Problems involving \(K_a\) Generally, the problem usually gives an initial acid concentration and a \(K_a\) value. From there you are expected to know: • How to write the \(K_a\) formula • Set up in an ICE table based on the given information • Solve for the concentration value, x. • Use x to find the equilibrium concentration. • Use the concentration to find pH. How to write the \(K_a\) formula The general formula of an acid dissociating into ions is \[HA_\] This can be flipped to calculate pH from hydronium concentration: \[pH = -\log[H_3O^+]\] • An acidic solution is one that has an excess of \(H_3O^+\) ions compared to \(OH^-\) ions. • An basic (or alkaline) solution is one that has an excess of \(OH^-\) ions compared to \(H_3O^+\) ions. • A neutral solution is one that has equal concentrations of \(OH^-\) ions and \(H_3O^+\) ions. At 25 °C, we can correlate whether a solution is a...

Hydrogen atoms have a slight positive charge when bonded to an electronegative element. If there is less electron density associated with hydrogen, it becomes easier to ionize and the molecule becomes more acidic. Weak acids form when there isn't enough polarity between the hydrogen atom and the other atom in the bond to allow for easy removal of the hydrogen ion.

Alcohols The alcohols form a homologous series . Like all homologous series, the alcohols: • have the same general formula • differ by CH 2 in molecular formulae from neighbouring compounds • show a gradual variation in physical properties , such as their boiling points • have similar chemical properties Functional group The functional group in the alcohols is the hydroxyl group, –OH. It is responsible for the typical reactions of alcohols. Take care not to confuse the –OH group with the hydroxide ion, OH - . General formula The general formula for the alcohols is C n H 2n+1 OH (where n is the number of carbon atoms in the molecule). Worked example Decanol is an alcohol. Its molecules contain ten carbon atoms . Predict the formula of decanol and explain your answer. The formula is C 10 H 21 OH. This is because n = 10. So, 2n+1 = (2 × 10) + 1 = 20 + 1 = 21. Question Hexanol is an alcohol. Its molecules contain six carbon atoms. Predict the formula of hexanol. Reveal answer down Reactions of alcohols The alcohols undergo complete combustion to form carbon dioxide and water. For example, ethanol is used as a fuel: Ethanol + oxygen → carbon dioxide + water C 2 H 5 OH + 3O 2 → 2CO 2 + 3H 2 O However, the alcohols can also be chemically oxidised , without combustion in oxygen, to produce carboxylic acids . For example, ethanol can be oxidised to ethanoic acid using an oxidising agent . It is easier to understand what happens if ethanol is shown as CH 3 CH 2 OH in the balanced eq...

This is the chemical structure of boric acid: boron (pink), hydrogen (white) and oxygen (red). LAGUNA DESIGN / Getty Images Boric Acid: H 3BO 3 Also known as: acidum boricum, hydrogen orthoborate Boric acid may be used as a disinfectant or pesticide. It's usually found as a white crystalline powder. This is the chemical structure of carbonic acid. LAGUNA DESIGN / Getty Images Carbonic Acid: CH 2O 3 Also known as: aerial acid, acid of air, dihydrogen carbonate, kihydroxyketone. Solutions of carbon dioxide in water (carbonated water) may be called carbonic acid. This is the only acid excreted by the lungs as a gas. Carbonic acid is a weak acid. It is responsible for dissolving limestone to produce geological features such as stalagmites and stalactites. Citric acid is a weak acid found in citrus fruits and used as a natural preservative and to impart a sour flavoring. Atoms are represented as spheres and are colour-coded: carbon (grey), hydrogen (white) and oxygen (red). LAGUNA DESIGN / Getty Images Citric Acid: H 3C 6H 5O 7 Also known as: 2-Hydroxy-1,2,3-propanetricarboxylic acid. Citric acid is a weak organic acid that gets its name because it is a natural acid in citrus fruits. The chemical is an intermediate species in the citric acid cycle, which is key for aerobic metabolism. The acid is widely used as a flavoring and acidifier in food. Pure citric acid has a tangy, tart flavor. This is the chemical structure of hydrofluoric acid: fluorine (cyan) and hydrogen (white). ...
