What happens when dilute sulphuric acid is added to copper oxide?

When dilute sulphuric acid is added to copper oxide, a chemical reaction occurs, resulting in the formation of copper sulfate and water. The reaction can be represented by the equation: CuO + H2SO4 → CuSO4 + H2O.


When silver coloured metal is added to dilute sulphuric acid solution?

When silver metal is added to dilute sulphuric acid solution, a redox reaction takes place. The silver metal reacts with the sulfuric acid to produce silver sulfate and hydrogen gas. The reaction can be represented by the following equation: 2Ag(s) + H2SO4(aq) -> Ag2SO4(aq) + H2(g)


What happens when dilute sulfuric acid is added over zinc granules?

coz when we dilute zinc granules are reacted with dilute HCl (hydrochloric acid), zinc chloride i.e. ZnCl2 is formed along with the evolution of hydrogen gas H2. the presence of hydrogen gas can be tested by bringing a naked flame to the mouth of the test tube. Hydrogen gas burns with a pop sound.


What happens when dilute sulphuric acid is added to zinc?

When dilute sulfuric acid is added to zinc, a chemical reaction occurs in which zinc reacts with the sulfuric acid to form zinc sulfate and hydrogen gas. The hydrogen gas is released as bubbles, and the zinc sulfate remains dissolved in the solution.
