Answer:
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.
