Question
An aqueous solution of volume 500 ml, when the reaction 2Ag+ (aq) + Cu(s) $\rightleftharpoons$Cu2+ (aq) + 2Ag(s) reached equilibrium, the concentration of Cu2+ ions was x M. To this solution, 500 ml of water is added. At the new equilibrium, the concentration of Cu2+ ions would be
Options
A.2x M
B.x M
C.between x and 0.5x M
D.less than 0.5x M
Solution
If equilibrium were not disturbed, [Cu2+]final = x/2 . But as equilibrium will shift backward, its concentration will decrease further.
