Question

Differentiate reduction and oxidation. Explain any three types of remix reaction with suitable examples

Answer 1

Answer:

Reduction - (i) Addition of Hydrogen. (ii) Addition of Electropositive         element. (iii) Gain of electrons.

Oxidation - (i) Addition of Oxygen. (ii) Addition of Electronegative element.

(iii) Loss of electrons.

The 3 types of Redox action are:-    

(i) Combination Reaction - It is a type of reaction where any two reactants form only one product.

Ex- 2H₂ + O₂ → 2H₂O

(ii) Decomposition Reaction -  It is a type of reaction where there is only one reactant and no. of products is either 2 or more than 2.

Ex- CaCO₃ → CaO + Co₂

(iii) Displacement Reaction - It is a chemical change in which a more active element displaces a less active element from its salt solution.

Ex- 2KI + Cl₂ → 2KCl + I₂
