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.
