Is pKa same as pH?
Difference Between pKa and pH pKa is the negative value of the logarithm of Ka. pH is the logarithmic value of the inverse of H+ concentration. pKa indicates whether an acid is a strong acid or a weak acid. pH indicates whether a system is acidic or alkaline.
What is pKa vs pH?
The logarithm gives a simple value which is very easy to handle. The main difference between pKa and pH is that pKa indicates the dissociation of an acid whereas pH indicates the acidity or alkalinity of a system.
Is pKa equal to pH?
When the moles of base added equals half the total moles of acid, the weak acid and its conjugate base are in equal amounts. The ratio of CB / WA = 1 and according to the HH equation, pH = pKa + log(1) or pH = pKa.
