Question
Write one equation for decomposition reactions where energy is supplied in the form of electricity.
Solution
Decomposition reaction involving absorption of electrical energy,
- \[\ce{\underset{Alumina}{2Al2O3_{(l)}} ->[Electric current] \underset{Aluminium}{4Al_{(l)}} + \underset{Oxygen}{3O2_{(g)}}}\]
- \[\ce{2H2O_{(l)} ->[electricity] 2H2_{(g)} + O2_{(g)}}\]

The white solid compound A decomposes quite rapidly on heating in the presence of a black substance X to form a solid compound B and a gas C. When an aqueous solution of compound B is reacted with silver nitrate solution, then a white precipitate of silver chloride is obtained along with potassium nitrate solution.

Two metals X and Y form the salts XSO4 and Y2SO4, respectively. The solution of salt XSO4 is blue in colour whereas that of Y2SO4 is colourless. When barium chloride solution is added to XSO4 solution, then a white precipitate Z is formed alongwith a salt which turns the solution green. And when barium chloride solution is added to Y2SO4 solution, then the same white precipitate Z is formed alongwith colourless common salt solution.
