Ionic Equilibrium

Dilution processes of different aqueous solutions; with water, are given in LIST-I. The effects of dilution of the solutions on [H+] are given in LIST-II (Note: Degree of dissociation (α) of weak acid and weak base is < < 1; degree of hydrolysis of salt < < 1;(H+) represents the concentration of H+ ions)

List - I	List - II
P. (10 mL of 0.1 M NaOH+20mL of 0.1 M acetic acid) diluted to 60ML	1. the value of [H+] does not change on dilution
Q. (20mL of 0.1 M NaOH+20mL of 0.1 M acetic acid) diluted to 80mL	2. the value of [H+] changes to half of its initial value on dilution
R. (20mL of 0.1 M HCl+20mL of 0.1 M ammonia solution) diluted to 80ML	3. the value of [H+] changes to two times of its initial value on dilution
S. 10mL saturated solution of Ni(OH)2 in equilibrium with excess solid Ni(OH)2 is diluted to 20mL (solid Ni(OH)2 is still present after dilution)	4. the value of [H+] change to 1 √2 times of its initial value on dilution
	5. he value of [H+] changes to √2 times of its initial value on dilution

Match each process given in LIST-I with one or more effect(s) in LIST-II. The correct option is

	P	Q	R	S
A)	4	2	3	1
B)	4	3	2	3
C)	1	4	5	3
D)	1	5	4	1
