What is the ph of a koh solution that has [h+] = 1.87 × 10–13 m?

pH = 12.73

Explanation:

pH of a solution is defined as the log to base 10 of the hydrogen ion (H+) concentration of the solution.

In the question above,

H+ = 1.87×10⁻¹³M

pH = -log[H+]

pH = -log(1.87×10⁻¹³)

pH = -(-12.73)

pH = 12.73

The pH of a 1.87×10⁻¹³ KOH solution is 12.73

sorry i was late, but i don't know what assignment your talking about, i'm in flvs as well, im in earth space science. but u are behind pace bc every class should be in the 3's or 4'
