### pH?calculating ph

How can you calculate pH using the Nernst equation?

Typically, you would arrange the Nernst equation in order to solve for Q, the reaction quotient, and then if the problem gives you the concentrations of other species, you set Q = [P]/[R], and solve for the concentration of [H+] ions. Then to find pH you take -log[H+].

Ahh I see, thanks for the help!
