Question

chemical reaction takes place when iron dust is added into copper sulphate solution but no reaction takes place when copper dust is added into ferrous sulphate solution why ~

Answer 1

because iron dust react with visit but iron dust doesn't react with fe2so4 solution,so any reaction doesn't take place

Answer 2

Answer:Iron is more reactive than copper

Explanation:

Refer to the reactivity series:

Since Iron is more reactive than copper, that means it has a greater tendency to lose electrons and form positive ion, displacing copper ion in copper sulphate solution.

However, since copper is below iron in the reactivity series, it is less reactive than iron and therefore unable to displace the ferrous ion (
