Question

What is the degree of ionization of hydrazoic acid, HN3, in an aqueous solution that is 0.33 M HN3 and 0.017 M HCIO4. Report your answer to 2 sig figs, but do NOT include units.

Answer 1

The degree of ionization of hydrazoic acid, HN3, in the aqueous solution is approximately 5.2%.

Step-by-step explanation:

The degree of ionization of hydrazoic acid, HN3, can be calculated using the formula:

Degree of Ionization = ([H3O+]/[HA]) * 100%

We are given the concentration of hydrazoic acid (HN3) as 0.33 M, and the concentration of perchloric acid (HCIO4) is 0.017 M. In this case, HCIO4 acts as a strong acid that fully ionizes, so we can assume that the concentration of [H3O+] is equal to the concentration of HCIO4.

By substituting the values into the formula: (0.017 M / 0.33 M) * 100%

The degree of ionization of hydrazoic acid in the aqueous solution is approximately 5.2%.
