Question

the acetate ion is the conjugate base of the weak acid acetic acid. the value of ( k_{b} ) for ( mathrm{ch}_{3} mathrm{coo}^{-} ) is ( 5.56 \times 10^{-10} ). write the equation for the reaction that goes with this equilibrium constant. it is not necessary to include states such as (aq) or (l)

Explanation:

Step1: Recall the definition of \(K_b\)

\(K_b\) is the base - dissociation constant. For a base \(B\), the general reaction is \(B + H_2O
ightleftharpoons BH^+ + OH^-\).

Step2: Apply the definition to acetate ion (\(CH_3COO^-\))

When acetate ion (\(CH_3COO^-\)) acts as a base, it accepts a proton (\(H^+\)) from water. The reaction is \(CH_3COO^-+H_2O
ightleftharpoons CH_3COOH + OH^-\)

Answer:

\(CH_3COO^-+H_2O
ightleftharpoons CH_3COOH + OH^-\)
