After I had to do about 50 different examples of these in my chemistry class, I decided to make small program in TI-Basic that solves for the pH of strong/weak acids and bases. To do the weak acids calculations, you need to provide the pKa or pKb, and the concentration of the acid/base. It uses the assumption that the concentration of H+, OH- in weak acids/bases tends to zero, and solves it without using the quadratic equation, therefore it’s not fully accurate, but its enough for the requirements of the IB. You need a calculator that supports TI-Basic, and means to transfer the program from the computer to the calculator.
