Answer to Question #49085 in Physical Chemistry for palashmura
A Zn rod is dipped in 100ml 1M solution so that molality of Cu2+ change to 0.7M.the molality of SO4 ion at this stage will be
When immersed in asolution of the rod, sulfate ions can not participate in the reaction.
Zn + Cu2+ => Zn2+ + Cu
Therefore, the concentration of sulfate ions stays unchanged.
