Question

The pH of an acidic solution is 2.83. What is [H*]?

Answer 1

0.001464 M, or 1.464 × 10^(-3) M.

Step-by-step explanation:

[H+] = 10^(-pH)

In this case, the pH of the acidic solution is 2.83. Plugging this value into the equation, we get:

[H+] = 10^(-2.83)

Using a calculator, we can find that 10^(-2.83) is approximately 0.001464.

Therefore, the concentration of hydrogen ions in the acidic solution is approximately 0.001464 M, or 1.464 × 10^(-3) M.
