A) 4.9
B) 5.0
C) 7.0
D) 10.0
Correct Answer: C
Solution :
Ammonium acetate is a salt of weak acid and weak base. When solutions of such salts diluted resulting pH of solution is calculated from following relationship \[pH=7+\frac{1}{2}p{{K}_{a}}-\frac{1}{2}p{{K}_{b}}\] \[\because \] \[p{{K}_{a}}\simeq p{{K}_{b}}\] (given) \[\therefore \] pH of diluted solution =7You need to login to perform this action.
