Hughes · Answer 1

x = 1 x 10⁻²

Explanation:

Since the pH is the same in both cases, the two expressions for pH can be set equal to each other:

pH = 4 + log (x) = - log[H⁺]

The hydrogen ion concentration ([H⁺]) is 0.01 M, so this value can be substituted in the equation:

4 + log (x) = - log (0.01)

4 + log (x) = 2

log (x) = - 2

x = 10⁻²
