Question

what kind of reaction is this:

3CuSO4 + 2 Al --> 3Cu + Al2(SO4)3

is it a double replacement or a redox reacton?

Answer 1

✔ Recommended Answer

Answer #1

Here only one anion is getting exchanged.

SO42- is getting exchanges from Cu to Al.

So, it is single replacement reaction.

It is not a double replacement reaction.

Oxidation state of Cu in reactant is +2

Oxidation state of Cu in product is 0

So, Cu is reduced

Oxidation state of Al in reactant is 0

Oxidation state of Al in product is +3

So, Al is oxidised

Since both oxidation and reduction is taking place, this is redox reaction

Answer: redox
