A monoprotic weak acid (HA) has a pKa value of 4.962. Calculate the fraction of HA in each of its forms (HA, A^-) at pH 6.246.
Henderson - Hasselbalch Equation
The Henderson - Hasselbalch equation is used to determine the pH of a buffer solution. According to the Henderson - Hasselbalch equation the pH of a buffer solution depends on the acid strength
of the solution and the logarithm of the ratio of its base to acid.
