Question

What is the pH of a substance that has a hydrogen ion concentration of 8.8

x 10^-2 M? (round to 2 decimals) *

Answer 1

Answer: 1.05

Step-by-step explanation:

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

i.e pH = -log (H+)

Since hydrogen ion ( H+) concentration = 8.8 x 10^-2 M = 0.088M

Thus, pH = -log (0.088M)

pH = - ( -1.055)

pH = 1.055

pH = 1.05 (pH value is rounded to 2 decimals)

Thus, the substance is strongly acidic since its pH is 1.05.
