This may be something that people encounter for the first time and they do not know the answer to this question immediately. If you have always been fascinated with Science then you may already be aware of w hat is pKa. This is used in order to show the acidity level of certain acids, particularly weak acids. Usually, the value of the pKa may vary. The lower the pKa value is, the stronger the value of the acid is. This also means that the higher the pKa value is, the stronger and more stable the conjugate base is. There are different acids and bases in this world, stronger acids will always remain constant but there are a lot of weak acids that can change in form. Ka is known as acid disassociation constant. This means that it measures the strength of the acid in the whole solution. More often than not, the Ka is written in quotients of equilibrium concentrations.
