Given the following information:

hydrocyanic acid = HCN

acetic acid = CH3COOH

CH3COOH is a stronger acid than HCN

(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.054 M aqueous hydrocyanic acid and sodium acetate are mixed. It is not necessary to include states such as (aq) or (s).

______ + _______ = ______ + ________

(2) Which is the strongest base, CN- or CH3COO- ?

(3) At equilibrium (products or reactants) the will be favored?

Solutions

Expert Solution

Weak acid have stronger conjugate base.

here CH3COOH is a stronger acid than HCN.

so CN- is stronger conjugate base than CH3COO-.

(1)  net ionic equation is

HCN (aq) + CH3COO- (aq) .<.............> CH3COOH (aq) + CN- (aq)

(2) strongest base is CN-.

(3) At equilibrium reactants the will be favored.
