Con · Answer 1

pH = 3, 00 (acidic solution), pOH = 7,00

Explanation:

The pH indicates the acidity or basicity of a substance. PH values between 0 and less than 7 indicate acidic solutions, 7 neutral and higher than 7 to 14 basic. It is calculated as

pH = - log (H 30+)

pH = - log (0.001)

pH=3, 00 (the solution is acidic because the pH is less than 7,00)

We know that the sum of the pH and pOH is 14, so we solve pOH:

pH + pOH = 14

3, 00 + pOH=14

pOH = 14 - 3,00 = 7, 00
