Question

Q 10-A zinc plate was put into a solution of copper sulphate kept in a glass conare
was found that the blue colour of the solution gets fader and fader with the passage of
time. After a few days, when the zinc plate was taken out of the solution, a number of
holes were observed on it.
(i) State the reason for changes observed on the zinc plate
(ii) Write the chemical equation for the reaction involved.
iii) Name another element which will show SAME OBSERVATIONS Justify with
equation

Answer 1

Answer:

Explanation:

1. ZINC PLATE ACTUALLY DISPLACED COPPER FROM CUSO4 TO FORM ZNSO4 AND Cu. zinc sulphate(ZNSO4) IS COLOURLESS AND SO THE BLUE COLOUR OF COPPER SULPHATE SOLUTION FADED AWAY. COPPER GOT DEPOSITED OVER THE ZINC PLATE.

2.Zn+CuSO4→ ZnSO4+ Cu. DISPLACEMENT REACTION. BECAUSE ZINC IS MORE REACTIVE THAN COPPER

3. take aluminium.

2Al+3CuSO4→Al2(so4)3+3Cu because aluminium is more reactive than copper. HOPE HELPED YOU.
