Question

In an experiment 2.65 g of zinc displaced 2.58 g of copper from copper sulphate solution. If equivalent weight of copper is 31.75, calculate that of zinc.​

Answer 1

Answer:

wt. of Cu liberated/wt. of zn reacted=equivalent wt. of Cu/eq. wt. of zn

So, 1/1.03=Eq.wt of Cu/32.5

=> Eq. wt of Cu=32.5×1/1.03=31.55

hope it helps
