Solution

The reaction of metals with acid and base
The metal reacts with an acid to form its corresponding salt along with hydrogen gas.
The general chemical reaction is as follows,
$Metal + Acid \to Salt + H_{2} (g)$
The metal reacts with a base to form its corresponding salt along with hydrogen gas.
The general chemical reaction is as follows,
$Metal + Base \to Salt + H_{2} (g)$
The gas produced burns with a pop sound, confirming the gas to be hydrogen gas.
The metal does not react with salt.
The reaction of metal with an acid
When zinc granules are added to the solution of sulphuric acid then zinc sulfate and hydrogen gas are formed as the product.
The chemical reaction is as follows,
$Zn (s) + H_{2} {SO}_{4} (aq) \to {ZnSO}_{4} (aq) + H_{2} (g)$
When zinc granules are added to the solution of hydrochloric acid then zinc chloride and hydrogen gas are formed as the product.
The chemical reaction is as follows,
$Zn (s) + 2 HCl (aq) \to {ZnCl}_{2} (aq) + H_{2} (g)$
When zinc granules are added to the solution of nitric acid, then zinc nitrate is formed as the product.
The chemical reaction is as follows,
$4 Zn (s) + 10 {HNO}_{3} (aq) \to 4 Zn {({NO}_{3})}_{2} (aq) + 5 H_{2} O (g) + N_{2} O (g)$
Reaction of metal with a base
When zinc granules are added to the solution of sodium hydroxide, sodium zincate, and hydrogen gas is formed as the product.
The chemical reaction is as follows,
$Zn (s) + 2 NaOH (aq) \to {Na}_{2} {ZnO}_{2} (aq) + H_{2} (g)$
The reaction of metal with a salt
Zinc granules do not react with salt, i.e, sodium chloride.
