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.
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.
The pure form of sodium hydroxide is solid. Compared to the pure form, the aqueous form of the liquid is actually many times more volatile. For this very reason, it is advised that the bottles used to keep samples of NaOH be kept closed.
