acid- and base reaction Need help solving this question

Question

hydrocyanic acid	=	HCN
benzoic acid	=	C6H5COOH

C₆H₅COOH is a stronger acid than HCN

 Write the net ionic equation for the reaction that occurs when equal volumes of 0.070 M aqueous hydrocyanic acid and sodium benzoate are mixed. It is not necessary to include states such as (aq) or (s).

(2) Which is the strongest base, CN- or C6H5COO- ?

 (3) At equilibrium the _________sproducts will be favored.

reactants or products

2)

hydrofluoric acid	=	HF
acetic acid	=	CH3COOH

HF is a stronger acid than CH₃COOH

(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.088 M aqueous hydrofluoric acid and sodium acetate are mixed. It is not necessary to include states such as (aq) or (s).

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

 

Answer 1

HCN(aq) + C6H5COO^-(aq) ==> C6H5COOH(aq) + CN^-(aq)

Since C6H5COOH is a stronger acid than HCN, CN^- will be the stronger base

At equilibrium the REACTANTS will be favored

Try the other by yourself.
