Answer to Question #112242 in General Chemistry for Lauren Barad

Question

Vinegar is a weak acid, which means that when placed in solution very few ions are produced. This makes the solution a weak conductor of electricity, thus its designation as week. Answer the following questions below based on vinegar’s, acetic acid, dissociation.

Reaction: CH3COOH(l)+ H2O(l) ⇋ CHCOO- (aq) + H3O+ (aq)

Heating the reaction causes it to conduct more electricity (produce more ions). Based on this information is the reaction endothermic or exothermic? *

Answer 1

It is classified as a weak acid since it only partially dissociates in solution, but concentrated acetic acid is corrosive and can attack the
