The pH level of a solution measures how acidic or basic the solution is. Values between 0 and 7 are considered acidic while values between 7 and 14 are considered basic. The pH is calculated by using the equation pH=−log[H3O+]. The notation [H3O+] represents the concentration of hydronium ions, which is measured in units of moles per liter, M.
What is the pH level of a solution if [H3O+]=3.4×10^−3M?
