Question

An aqueous solution of volume 500ml, when the reaction: ( ) ( ) ( ) 2 2 ( ) 2 ag aq cu s cu aq ag s + + + + , reached equilibrium, the concentration of 2 cu + ions was x m. to this solution, 500 ml of water is added. at the new equilibrium, the concentration of cu2+ ions would be

Answer 1

, the `[Cu^(2 +)]` was `'a'M`. If `500 ml` water is further added, at the equilibrium `[Cu^(2+)]` will be `:` .
