Copper sulphate hydrates as CuSO4.nH2O, where n can range from 1 to lớn 7. In both agricultural and non-agricultural environments, it is used as a fungicide, algaecide, and herbicide. HCl is found in the digestive systems of most animal species, including humans, as a component of gastric acid.

In the following section of the article, let us discuss the mechanism of the reaction between HCl and CuSO4, the reaction enthalpy, the type of reaction, product formation, and ví on.

## What is the product of HCl and CUSO4?

When concentrated HCl is added to lớn a much-diluted solution of CuSO4, the pale xanh lơ solution gradually turns greenish-yellow due to lớn the formation of a copper chloride complex (tetrachlorocuprate (II)).

CuSO4 + 2HCl → CuCl2 + H2SO4

• A=2, B=1, C=1, D=1
• As a result, the overall balanced equation for the preceding reaction is,
• 2HCl + CuSO4 → H2SO4 + CuCl2

## HCl + CuSO4 titration

Titration of HCl + CuSO4 is not possible for these reasons.

• HCl is highly acidic.
• CuSO4 is a solid that is white or off-white in color. In the liquid state it contains a strong acid of (H2SO4) and a weak base [Cu(OH)2] salt. As a result, its solution has a pH of 7 ie, highly acidic.
• Two acidic solutions cannot be used for titration.
