Question
Pure water is added into the following solutions causing a 10% increase in volume of each. The greatest % change in pH would be observed in which case (A), (B), (C) or (D) ?
Options
A. 0.1 M NaHCO3
B.0.2 M NaOH
C.0.3 M NH3 - 0.2 M NH4+ system
D.0.4 M CH3COONH4
Solution
(A) pH of NaHCO3 is independent of dilution.
(C) pH of buffer solution is approximately ramains constant with dilution.
(D) pH of salt of WA & WB is independent of dilution.
