A solution is prepared by dissolving 0.23 moles of chloroacetic acid and 0.27 moles of sodium chloroacetate in water sufficient to yield 1.00L of solution. The addition of 0.05 mole of HCl to this buffer solution causes the pH to drop slightly. The pH does not decrease drastically because the HCl reacts with the.........present in the buffer solution. The Ka of chloroacetic acid is 1.36*10^-3.
Homework Answers
The answer is:
the PH does not decrease drastically because the HCl reacts with the CHLOROACETATE ion present in the buffer solution.
HCl dissociates as H+ + Cl-
chloroacetate is ClCH2COO-
the reaction is : ClCH2COO- + H+ = ClCH2COOH
as the H+ is getting reacted so PH is droping slightly.
