Answer:


\huge{ \boxed{3.8}}

Step-by-step explanation:

pH is defined as the negative logarithm of the hydrogen ion
[{H}^(+)] or hydroxonium ion(
{H_3O}^(+)) concentration of a solution. That is


\bold{pH = -log([{H}^(+)])}

From the question


[{H}^(+)] = 1.5 × 10-⁴ M


pH = - log(1.5 * {10}^( - 4) ) \\ = 3.823 \approx3.8

We have the final answer as

3.8
