Acids and Bases react with metals to form salt and hydrogen gas.

Acid/ Base + Metals → Salt + Hydrogen Gas

 

Example 1

When Zinc (Zn) reacts with dilute Sulphuric Acid (H 2 SO 4 ), it produces a salt called Zinc Sulphate (ZnSO 4 ) and Hydrogen Gas.

Zn(s) + H 2 SO 4 (aq) → ZnSO 4 (aq) + H 2 (g)

 

 

Example 2

When Sodium hydroxide (NaOH, a base) is heated with Zinc (Zn, a metal),it forms Sodium Zincate (Na 2 ZnO 2 , a salt) and Hydrogen Gas (H 2 ). This hydrogen gas produces a pop sound
