Question

28 What is the concentration of hydrogen ions [H+] in a solution that has a pH of 4.32? (1 Point) a. 4.8 x 10-5M b. 6.2 x 10-4M C. 5.1 x 10-4M d. 8.6 x 10-5M​

Answer 1

Answer: The concentration of hydrogen ions in the given solution is
`6.2 * 10^(-4)`.

Step-by-step explanation:

Given : pH = 4.32

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

`pH = - log [H^(+)]`

Substitute the value into above formula as follows.

`pH = - log [H^(+)]\\= - log (4.32)\\= 6.2 * 10^(-4)`

Thus, we can conclude that the concentration of hydrogen ions in the given solution is
`6.2 * 10^(-4)`.
