WebA pKa value is used to determine the pH of a solution containing a weak acid. Recall that Kp is defined for a general reaction: nA+mB --> pC + qD as [D]^q[C]^p/[A]^n^m, where all … WebCalculate the value of Kin for the indicator Draw a second best line through the results, use this to obtain a second value of pkin from this value calculate a deviation on both pkin and Kin NOTE: Although computer generated graphs are often acceptable and sometimes even preferred, the graph for this experiment must be plotted manually!

WebThis is the pH range over which the indicator changes colour. A guide is to use pKin ± 1. The ideal choice of indicator for a titration is one which has a pKin value at the equivalence point. Equivalence point This is the point (pH) at which stoichiometric amounts (equivalent moles) of acid and alkali have reacted exactly with each other. WebJan 30, 2024 · Relating pH and pKa With the Henderson-Hasselbalch Equation. If you know either pH or pKa, you can solve for the other value using an approximation called the Henderson-Hasselbalch equation: pH = pKa + log ( [conjugate base]/ [weak acid]) pH = pka+log ( [A - ]/ [HA]) pH is the sum of the pKa value and the log of the concentration of … jessica harvey pa-c
