The pH of a solution is defined as the negative logarithm (base 10) of the concentration of hydrogen ions (H+) in moles per liter (M).
Mathematically, pH = -log[H+]
Rearranging this equation, we get:
[H+] = 10^(-pH)
Substituting the given value of pH = 2.42 into this equation, we get:
[H+] = 10^(-2.42)
[H+] = 6.307 x 10^(-3) M
Therefore, the concentration of protons [H+] for a solution with pH = 2.42 is 6.307 x 10^(-3) M.
