REACTION OF ACIDS AND BASES WITH METALS

 Reaction of Acid with metal

When metals react with acid, generally metal will displaces hydrogen atoms from the acid as hydrogen gas and forms a compound called salt. That’s 

Acid + metal —> salt + hydrogen gas

Examples for reaction of acid with metal 

1. Zinc + sulphuric acid—>  zinc sulphate + hydrogen 

Zn + H₂SO₄ —> ZnSO₄ + H₂

2.Magnesium + hydrochloric acid—> magnesium chloride + hydrogen gas

Mg + 2HCl—> MgCl₂ +H₂

Reaction of base with Metal 

Similarly, Base react with metal and produce hydrogen gas and salt.

Base + Metal—> Salt + Hydrogen Gas

Example for reaction of base with metal 

1. Reaction of sodium hydroxide  with zinc to produce sodium zincate and hydrogen gas

NaOH + Zn —> Na₂ZNnO₂ + H₂

2. Sodium hydroxide in presence of water, react with aluminium and produce sodium aluminate and hydrogen gas 

2NaOH + 2H₂O + 2Al —> 2NaAlO₂ + 3H₂
