Question

what types of reaction is the following ; H2s + CuSO4 ----------> CuS + H2SO4

Answer 1

Hey there,

In the given reaction:-

H₂S+CuSO₄→CuS+H₂SO₄

The ions SO₄²⁻ and S²⁻ gets interchanged with Copper(Cu) and Hydrogen(H) so the given reaction is an example of double displacement reaction.

Answer 2

Answer:

The given reaction is a precipitation reaction which is a form of double-displacement reaction...

Explanation:

Let us separate the cations (+ve ions) and the anions (-ve ions) of the reactants...

The positive ion in the reactants are $H_{2} ^{+}$ and $Cu^{+\\}$

The negative ions in the reactants are $S^{-}$ and $SO_{4} ^{2-}$

When interchanged, the products so formed are CuS and $H_{2}SO_{4}$

On interchanging the ions, since, both products are compounds, we can say it is a double displacement reaction.

Then, we observe that CuS is the precipitate remaining in the aqueous solution of  $H_{2}SO_{4}$. so we can also conclude that it is a precipitation reaction which is a type of double displacement reaction.
