WebbFor dilute (ideal) solutions, the standard state of the solute is 1.00 M, so its molarity equals its activity. That's why for most problems that assume ideal solutions we can use the base 10 logarithm of the molar concentration, not the activity. Why do we need pH at all? pH is a measure used to specify acidity or basicity of an aqueous solution. WebbpOH = -log 10 [OH-] = -log 10 [3.16 × 10-4] = 3.5 Since this value is the same as that given in the question, we are confident our answer is correct.
