Succinic acid is diprotic: the acid (H2C4H4O4) reacts with two of its hydrogens to give C4H4O42-. As with aldehydes and ketones, carboxylic acid formulas can be written to show the carbon-to-oxygen double bond explicitly, or the carboxyl group can be written in condensed form on one line. Because soaps are prepared by the alkaline hydrolysis of fats and oils, alkaline hydrolysis of esters is called saponification (Latin sapon, meaning soap, and facere, meaning to make). Even so, compounds in this group react neither like carboxylic acids nor like ethers; they make up a distinctive family. The reaction equation will be as follows. Carboxylic acids having one to four carbon atoms are completely miscible with water. ), more soluble because there is more extensive hydrogen bonding. Ester molecules are polar but have no hydrogen atom attached directly to an oxygen atom. The explosive nitroglycerin (glyceryl trinitrate) is an ester formed from glycerol and nitric acid. To make things easier, just work in molarity. The addition of the NaOH will "use up" 0.01 mol of propanoic acid and "create" 0.01 mol of propionate. write an equation for the reaction of a carboxylic acid with a base, such as sodium hydroxide.
