The answer to your question is pH = 3.3

Explanation:

Data

pH = ?

[HNO₂] = 0.00052 M

pH measures the [H⁺] in a solution. It has a range of 0 to 14. Acids have a pH from 0 to 6.9, a neutral solution has a pH of 7.0 and alkalis have a pH from 7.1 to 14.

Formula

pH = - log [H⁺]

Substitution

pH = - log[0.00052]

Simplification

pH = - (-3.284)

-Result

pH = 3.3
