Question

Rearrange the following equation and solve for x when the hydrogen ion concentration is 0.01 M. pH=4+logx (Recall that pH=−log[H+]. Use the hints if you do not obtain one of the answers.) View Available Hint(s) Rearrange the following equation and solve for when the hydrogen ion concentration is 0.01 . (Recall that . Use the hints if you do not obtain one of the answers.) x=2 x=0.40 x=0.1 x=1×10−2

Answer 1

Answer:

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
