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?
