Question

Write balanced equations for the following: (i) NaCl is heated with sulphuric acid in the presence of MnO2. (ii) Chlorine gas is passed into a solution of NaI in water.

Answer 1

Hey Dear,

◆ Balanced reactions -

(i) When NaCl is heated with sulphuric acid in the presence of MnO2, it produces MnCl2 and NaHSO4.

4NaCl + MnO2 + 4H2SO4 --> MnCl2 + 4NaHSO4 + 2H2O + Cl2

(ii) When chlorine gas is passed into a solution of NaI in water, sodium chloride is formed with liberation of Cl2 gas.

2NaI + Cl2 --> 2NaCl + I2

Hope that helped you..
