In respect to this, how do you find the ka value? Ph describes the acidity of a solution. At the equivalence point, the concentrations of the base and the acid are equal. • kb is related to the acid dissociation constant, ka, by the simple relationship pka + pkb = 14, where pkb. For example, the dissociation of a weak acid “ha” is written: The naoh is added as small increments of equal volume and at each step, the ph of the solution is measured and a titration curve is prepared as mentioned above.

The pka of the solution is the negative logarithm of the ka.

At half the equivalence point: Remember your definitions for logarithmic functions. In respect to this, how do you find the ka value? Let us find its k a value from the above expressions. Take the negative log of ka to get pka: Find the ka for the equation:
