Question
The pH vlues of aqueous solutions of which of the following compounds does not change on dilution ?
Options
A.PhCOONH4
B.NH4CN
C.HCOONa
D.NH4Cl
Solution
Either buffer or salt of WA/WB solutions pH values does not change on dilution.
Since in buffer, on dilution both the concentration of WA or WB and their conjugate ions change, but their ratio remains same.
Hydrolysis of salts of WA/WB are independent on the concentration, so their pH values also does not change on dilution.
