Use the References to access important values if needed for this question.

Given the following information:

HNO2is a stronger acid than HCN

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

Given the following information:

C6H5COOH is a stronger acid than CH3COOH

(1) Write the net ionic equation for the reaction that occurs when equal volumes of 0.068 M aqueous acetic acid andsodium benzoate are mixed. It is not necessary to include states such as (aq) or (s).

(3) At equilibrium the _________reactantsproducts will be favored.

Explanation / Answer

HNO2(aq) + NaCN(aq) ----> HCN (aq) + NaNO2(aq) is molecular equation

net ionic equation is

H+ (aq) + CN -(aq) < ---> HCN (aq)

CH3COOH (aq)+ C6H5COONa (aq) <----> CH3COONa(aq) + C6H5COOH (aq) is molecular equation

Net ionic equation is

CH3COOH (aq) <---> CH3COO-(aq) + H+ (aq)

weak acid conjugate base is stronger.

Hence CH3COO- is stronger base.

3) at equilibrium reactants is favoured.
