The compound is -bromobutyric acid or 4-chlorobutanoic acid. What products are formed when a carboxylic acid is neutralized with a strong base? Further condensation reactions then occur, producing polyester polymers. In the poorly heated laboratories of the late 19th and early 20th centuries in northern North America and Europe, acetic acid often froze on the storage shelf. Answer (1 of 5): CH3COOH + NaOH CH3COONa + H2O Acetic acid is a weak electrolyte; sodium hydroxide is a strong electrolyte, so: CH3COOH + OH- CH3COO- + H2O Sodium acetate (ethanoate) is a salt formed from weak acid and strong base, so it hydrolysed in solution: CH3COO- + H2O CH3COOH + O. The compound is -chlorobutyric acid or 2-bromobutanoic acid. Sodium hydroxide is represented by the chemical formula NaOH. Reaction of propanoic acid with the given species is as follows.
