Question

Sulphuric acid reacts with cupric oxide to give:
A.Copper sulphate
B.Cuprous sulphate
C.No reaction
D.It converts to cuprous oxide

Answer 1

Hint: A chemical reaction occurs when one or more compounds, known as reactants, are changed into one or more distinct substances, known as products. The constituent atoms of the reactants are rearranged in a chemical reaction, resulting in the formation of various substances as products.

Complete answer:
Sulphuric acid - Sulfuric acid (American spelling) or sulphuric acid (Commonwealth spelling) is a mineral acid made up of the elements Sulphur, oxygen, and hydrogen. It's also known as oil of vitriol. It is a colorless, odorless, viscous liquid that is miscible in all concentrations with water.
Cupric oxide - The inorganic compound CuO, also known as copper (II) oxide or cupric oxide, has the formula CuO. It's a black solid that's one of copper's two stable oxides, the other being copper(I) oxide. Tenorite is the mineral name for it.
Chemical reaction –
\[{H_2}S{O_4} + CuO \to CuS{O_4} + {H_2}O\]
So, we conclude that Copper sulphate and water are formed when sulphuric acid combines with cupric oxide.
So, the final answer is option (A) i.e., Copper sulphate.
