Question

5 Example of acid- base reaction

Answer 1

HCl(aq) + Na(OH)(aq) → H2O + NaCl(aq)

H+ + OH− → H2O

H2SO4 + 2 NH4OH -->(NH4)2SO4+ 2HOH

2 NaOH + H2CO3 --> N2CO3 + 2 NaOH

HBr +KOH--> KBr+H2O

Hope it helped

Answer 2

Examples of acid base reaction are as follows -

• Reaction between sodium hydroxide and hydrochloric acid :

NaOH + HCl ---> NaCl + H2O

In this reaction,the base is sodium hydroxide (NaOH) and the acid is hydrochloric acid (HCl). They react with each other to form sodium chloride and water.

• Reaction between calcium hydroxide and hydrochloric acid :

Ca(OH)2 + HCl ----> CaCl2 + H2O

In this reaction,the base is calcium hydroxide and the acid is hydrochloric acid. They react with each other to form calcium chloride and water.

• Reaction between sodium carbonate and hydrochloric acid :

Na2CO3 + HCl ---> NaCl + H2O + CO2

In this reaction, the base is sodium carbonate and the acid is hydrochloric acid. They react with each other to form sodium chloride, water, carbon dioxide gas.

• Reaction between calcium carbonate and hydrochloric acid :

CaCO3 + HCl ----> CaCl2 + H2O + CO2

In this reaction,the base is calcium carbonate and the acid is hydrochloric acid. They react with each other to form calcium chloride, water and carbon dioxide gas.

• Reaction between calcium carbonate and sulphuric acid :

H2SO4 + CaCO3 ---> CaSO4 + CO2 + H2O

Hindi section, the acid sulphuric acid and the base is calcium carbonate.They react with each other to form calcium sulphate,water and carbon dioxide gas.
