Are these formulas correct?

pH + pOH = 14
pH = -log[H+]
pOH = -log[OH-]
[OH-] = 10^-pOH
pH = 10^-pH

    The definition of pH is: pH = -log 10[H^+] what is the defintion of the [OH^-]... is it pOH = -log 10[OH^-]? Yes!! pH = - log10 anything. pKa = -log Ka Pkb = -log Kb pKw = -log Kw = 14 PKsp = -log Ksp (solubility product) and so
