WHAT HAPPENS WHEN SULPHURIC ACID REACTS WITH ZINC METAL?
metal + acid -> metal salt + hydrogen
zinc + sulphuric acid -> zinc sulphate + hydrogen
see chemical equation below
It will dissolve
The zinc will react with sulphuric acid forming zinc sulphate dissolved in solution and releasing hydrogen gas.
Zn (s) + H2SO4 (aq) ---> ZnSO4 (aq) + H2 (g)
When we take the test tube containing zinc and sulphuric acid near a candle or a burner, we hear a pop sound. This shows the presence of Hydrogen .
Also, if we take the the test tube near a litmus paper, the color remains same. This shows that hydrogen is neither acidic nor basic in nature. It is neutral in nature.
