Hoping, you are looking for all the important
chemical reactions for class 10 for the upcoming CBSE board examination.
We will discuss all chemical reactions that
are very useful and important in the context of the NCERT science book. Before
learning all chemical reactions, you must know what is the trick of naming chemical reactions.

1. Displacement reaction between Zn and `H_2SO_4`
`Zn + H_2SO_4 →ZnSO_4 + H_2`
2. Reaction of photosynthesis
`6CO_2+6H_2O\overset{sunlight}\underset{cholrophyll}{\rightarrow} C_6H_12O_6 +6O_2`
3. Burning/combustion of natural gas
`CH_4 + 2O_2 →CO_2 + 2H_2O + \text{energy}`
4. Decomposition of Ferrous sulphate
`2FeSO_4 → Fe_2O_3 + SO_2 + SO_3`
5. Thermal decomposition of Lead nitrate
`2PbNO_3→ 2PbO + 4NO_2 + O_2`
6. Electrolysis of water
`2H_2O \overset\text{electric current}{\rightarrow} 2H_2 + O_2`
7. Double displacement reaction of Sodium sulphate with Barium chloride
`Na_2SO_4 + BaCl_2 → BaSO_4 + 2NaCl`
8. Rusting of Iron
`4Fe + 3O_2 + n.H_2O → 2Fe_2O_3.nH_2O`
9. Reaction of metal carbonate with an acid
`Na_2CO_3 + 2HCl \rightarrow 2NaCl +H_2O + CO_2`
10. Reaction of metal hydrogen carbonate with an acid
`NaHCO_3 + HCl → NaCl + H_2O +CO_2`
11. Formation of sodium hydroxide
`2NaCl + 2H_2O → 2NaOH + H_2 + Cl_2`
12. Formation of bleaching powder
`Ca(OH)_2 + Cl_2 \rightarrow CaOCl_2 + H_2O`
13. Formation of sodium zincate
`2NaOH + Zn → Na_2ZnO_2 + H_2`
14. Reaction of plaster of Paris with water
`CaSO_4.frac{1}{2}H_2O + 1\frac{1}{2}H_2O →CaSO_4. 2H_2O`
15. Thermit reaction
`Fe_2O3_ + 2Al → 2Fe + Al_2O_3 + heat`
16. Combustion reaction
`C+O_2 →CO_2 + heat and light`
`CH_4 +O_2 →CO_2 + H_2O + heat and light`
17. Conversion of alcohol into acetic acid
`CH_3-CH_2OH \overset\text{alkaline KMnO4 +heat}\underset{acidic K_2Cr_2O_7+heat}{\rightarrow}CH_3COOH`
18. Hydrogenation (formation of vegetable ghee)
`R_2C=CR_2 \overset{catalyst Ni}\underset{H_2}{\rightarrow} R_2HC- CHR_2`
19. Dehydration of ethanol (ethyl alcohol)
`CH_3- CH_2OH \overset{hot & con.H_2SO_4}{\rightarrow} CH_2=CH_2 + H_2O`
20. Formation of ester
`CH_3COOH + CH_3CH_2OH \overset{acid}{\rightarrow} CH_3COOCH_2CH_3 +H_2O`
21. Saponification
`CH_3COOC_2H_5 \overset{NaOH}{\rightarrow} C_2H_5OH + CH_3COONa`
