Question

A solution is prepared by dissolving 0.23 mol of hydrazoic acid and 0.27 mol of sodium azide in water sufficient to yield 1.00 L of solution.The addition of 0.05 mol of NaOH to this buffer solution causes the pH to increase slightly. The pH does not increase drastically because the NaOH reacts with the __________ present in the buffer solution. The Ka of hydrazoic acid is 1.9 x 10-5.

A.) H2O

B.) H3O+

C.) azide

D.) hydrazoic acid

E.) this is a buffer solution: the pH does not change upon addition of acid or base

Explanation / Answer

N3H(aq) + OH- (aq) <--> N3-(aq) + H2O (l) is the reaction.

Thus NaOH reacts with hydrazoic aic
