Answer: 3.60

Explanation:

pH is the negative logarithm of hydrogen ion concentration of a solution.

Mathematically, pH = - log (H+)

Since [H+] = 0.00025

Then, pH = - log (0.00025)

pH = - (-3.60)

pH = 3.6 (since the two minus signs will cancel out)

Thus, the pH of the solution is 3.6, making it an acidic solution
