FAQ (Frequently Asked Questions)

1. Before burning a magnesium ribbon in the air, why should it be cleaned

Magnesium ribbon must be cleaned before burning in the air, so as to remove the layer of MgO formed due to the reaction between magnesium and air. 

2. Why not immediately a wall acquires a white colour when a coating of slaked lime is applied to it?

When a solution of slaked lime is applied on the wall, CO2 gas present in the air slowly reacts with a thin layer of calcium hydroxide to form a thin layer of calcium carbonate, that is quite white. Therefore, the newly formed calcium carbonate impart a white look to the walls. 


Ca(OH)2 (aq) + CO2 (g) →  CaCO3 (s) + H2O (l)

3. Consider the following reaction:

2FeSO4 (s) → Fe2O3 (s) + SO2 (g) + SO3 (g)

Is it a redox reaction or not? If yes, why?

It is a redox reaction because ferrous (Fe3+) whereas SO2-4 is getting reduced to SO2.

4. Identify the oxidizing agent in the following equation.

MnO2 (s) + 4HCL à MnCl2 (aq) + Cl2 (g) + 2H2O

MnO2 is the oxidizing agent in the equation.
