Question

what happen when CuSo4+Fe added to 50ml of water

Answer 1

Zinc is higher up in the Electrochemical series than Copper and will thus displace Copper from CuSO4CuSO4 the instant it comes into contact with it’s solution. Adding water while the reaction is underway will only dilute the mixture and will have little or no effect on the rate of the reaction or it’s outcome.
