Simple Reactions of Carboxylic Acids as Acids

\( \newcommand\) • • • • • • • • This page looks at the simple reactions of carboxylic acids as acids, including their reactions with metals, metal hydroxides, carbonates and hydrogencarbonates, ammonia and amines. The acidity of the carboxylic acids Using the definition of an acid as a "substance which donates protons (hydrogen ions) to other things", the carboxylic acids are acidic because of the hydrogen in the -COOH group. In solution in water, a hydrogen ion is transferred from the -COOH group to a water molecule. For example, with ethanoic acid, you get an ethanoate ion formed together with a hydroxonium ion, H 3O +. This reaction is reversible and, in the case of ethanoic acid, no more than about 1% of the acid has reacted to form ions at any one time. (This is a rough-and-ready figure and varies with the concentration of the solution.) These are therefore weak acids. \[ CH_3COOH + H_2O \rightleftharpoons CH_3COO^- + H_3O^+\] This equation is often simplified by removing the water to: \[ CH_3COOH (aq) \rightleftharpoons CH_3COO^- (aq) + H^+\] However, if you are going to use this second equation, you must include state symbols. They imply that the hydrogen ion is actually attached to a water molecule. The pH of carboxylic acid solutions The pH depends on both the concentration of the acid and how easily it loses hydrogen ions from the -COOH group. Ethanoic acid is typical of the acids where the -COOH group is attached to a simple alkyl group. Typical lab solutions h...

Ethanoic Acid

Ethanoic Acid What is Ethanoic Acid? Ethanoic acid (CH 3COOH) belongs to the group of carboxylic acids and is commonly called as acetic acid. It is slightly heavier than water with a density of 1.05 g/cm 3. After adding 5-8% of acetic acid in water it becomes vinegar and is mostly used as preservatives in pickles. Acetic acid is the common name for Ethanoic acid.

Ethanoic acid is also referred to as glacial acetic acid because its melting point is 16 oC. Hence, it often freezes in winter when the climate is cold. Reactions of Ethanoic acids: Esterification reaction: • When carboxylic acid and alcohol react, the product formed is known as an CH 3COOH    +     CH 3CH 2OH   →  CH 3COOCH 2CH 3 (Ethanoic acid)     (Ethanol)                (Esters) • Esters have a sweet fruity smell. They are mainly used for making perfumes and synthetic flavouring agents. The reaction of esters with alkalis gives CH 3COOC 2H 5     + NaOH    →    C 2H 5OH + CH 3COONa Reaction with a base: • Ethanoic acid reacts with a base to give the salt and water just like other mineral acids. Reaction with carbonates and hydrogen carbonates: • Carbon dioxide, salt, and water are produced when ethanoic acid reacts with ca...

Trichloroacetic Acid

What is Trichloroacetic Acid? Trichloroacetic acid is an organic compound in which three hydrogen atoms of the methyl group of acetic acid get replaced by chlorine atoms. It is a white crystalline solid. It is also known as TCA, TCAA or trichloro ethanoic acid. But its systematic IUPAC name is trichloroacetic acid. As the name suggests, it's an analogue of acetic acid. It is a strong acid which is widely used in clinical chemical and biochemistry. Specially its salts and esters are very famous for their usage in cosmetics. Its salts and esters are called trichloroacetates. In 1839, French Chemist Jean – Baptiste Dumas discovered trichloroacetic acid. It is also called aceto - caustin. Its discovery gave a noticeable example to the theory of organic radicals and valances. This theory was based on the facts which were contrary to the beliefs of Swedish Chemist Jons Jakob Berzelius. Thus, Jean – Baptiste Dumas was the first chemist who criticized or questioned the results of the electro – chemical research of Jons Jakob Berzelius. Before the discoveries made by Dumas, results of electro – chemical research by Jons Jakob Berzelius were widely accepted at that time. It started a long debate between Jons Jakob Berzelius and Jean – Baptiste Dumas. Formula of Trichloroacetic Acid S. No. Formula of Trichloroacetic Acid 1. Empirical Formula C 2 HCl 3 O 2 2.

7.3: Names and Formulas of Acids

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.

Equation for Reaction Between Baking Soda and Vinegar

• The overall chemical reaction between baking soda (sodium bicarbonate) and vinegar (weak acetic acid) is one mole of solid sodium bicarbonate reacts with one mole of liquid acetic acid to produce one mole each of carbon dioxide gas, liquid water, sodium ions, and acetate ions. • The reaction proceeds in two steps. The first reaction is a double displacement reaction, while the second reaction is a • The baking soda and vinegar reaction can be used to produce sodium acetate, by boiling off or evaporating all the liquid water. How the Reaction Works The reaction between baking soda and vinegar actually occurs in two steps, but the overall process can be summarized by the following word equation: The carbon dioxide escapes the solution as bubbles. The bubbles are heavier than air, so the carbon dioxide collects at the surface of the container or overflows it. In a baking soda volcano, detergent usually is added to collect the gas and form bubbles that flow somewhat like lava down the side of the 'volcano.' A dilute sodium acetate solution remains after the reaction. If the water is boiled off of this solution, a supersaturated solution of sodium acetate forms.
