Question

Sodium chloride + manganese dioxide + sulphuric acid -> Sodium hydrogen sulphate + manganese sulphate + water + chlorine

Answer 1

For the given acid , you have to derive short formula with the respective value which are give below .

2NaCH+3H2SO4+MnIVO2->2

NaHSO4+MnIISO4+CI20+2H20 .

hence candidate can collect exact answer for the give formula about the product. Hence it provide better ideas with no risk and trouble of it.

Answer 2

NaCl + MnO₂ + H₂SO₄ → NaHSO₄ + MnSO₄ + H₂O + Cl₂

This reaction is not balanced. The reactants and products are given, thus to balance the reaction,

i) 2 Cl atoms at right side while 1 in left side.

Put a 2 before NaCl making the number of Cl atoms balanced.

ii) Now there are 2 Na atoms at left while 1 at right.

To balance it put 2 before NaHSO₄.

iii) Consider (SO₄) -- 3 units in right hand side, 1 in left hand side.

Put a 3 before H₂SO₄ in left hand side, thus number of (SO₄) units get balanced.

iv) Balance the excess H atoms at left side,

by putting a 2 before H₂O.

And thus the reaction as a whole gets balanced.

2NaCl + MnO₂ + 3H₂SO₄ = 2NaHSO₄ + MnSO₄ + 2H₂O + Cl₂
