Question

The H30+ concentration of a solution is equal to 0.8 M. What is the pH of the solution?

a.) pH = 0.1
b.) pH = 1.1
c.) pH = 2.1
d.) pH = 10.1

Answer 1

option A= pH = 0.1

Step-by-step explanation:

Given data:

Concentration of H₃O⁺ = 0.8 M

pH = ?

Solution:

pH = -log [H₃O⁺] H₃O⁺ = H⁺

pH = -log [0.8]

pH = - (-0.097)

pH = + 0.1
