The ph scale for acidity is defined by ph=−log10[h⁺] where [h⁺]is the concentration of hydrogen ions measured in moles per liter (m). a solution has a ph of 12.25. calculate the concentration of hydrogen ions in moles per liter (m). the concentration of hydrogen ions is moles per liter.

5.62 * 10^-13 moles per liter

Explanation:

The pH of a solution is the negative logarithm to base 10 of the concentration of hydrogen ions. What we simply do here is to input the information in the question into the equation:

pH=−log10[H⁺]

Here we know the pH but we do not know the concentration of the hydrogen ions.

12.25 = -log [H+]

log[H+] = -12.25

[H+] = 10^-12.25

[H+] = 5.62 * 10^-13 moles per liter
