WebJan 17, 2024 · If exactly one-half of the acid is dissociated, pKa = pH. Double-check whether the value you have is Ka or pKa. p in mathematics describes the negative logarithm with a base of 10. If you want to calculate the pH of a basic buffer, we recommend using the following modification: pH = 14 - pKb - log([B+]/[BOH]) WebTo find the pH of a solution given the hydrogen ion, H +, concentration in mol L-1: . Enter a number: for example 0.010 [H +] = mol L-1; Click the log button on the calculator shown on the right ; log 10 of = ; Since pH = -log 10 [H +] we need to multiply the number above by -1 pH = -1 × log 10 [H +] In effect this means we reverse the sign of the number:
