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)


1. which of the following is the correct equilibrium expression (Keq) for the dissociation of vinegar? *


Option alpha - K(eq) = ([CH3COOH)^1(H2O)^1) / ([CHCOO-]^1[H3O+]^1)


Option beta - K(eq) = 1 / ([CHCOO-]^1[H3O+]^1)


Option charlie - K(eq) = ([H3O+]^1[CHCOO-]^1) / ([CH3COOH]^1[H2O]^1)


Option delta - K(eq) = [H3O+]^1[CHCOO-]^1

Answer 1

Oh, mistaked.

K(eq)=$\prod$ [product]/$\prod$ [reagent].

Charlie option.
