A cation `A^(+4x)` and an anion `B^(-2x)` combine to form a compound. Similarly, `C^(+2x) and D^(-4x)` also combine to form a compound. When the molten compounds are subjected to electrolysis, the gaseous products obtained are in equimolar amounts. What should be the mole ratio of the compounds taken respectively?

Explanation

(i) application of criss-cross method
(ii) derivation of the formulae of both the compounds
(iii) determination of the ratio of the number of atoms of B and D, present in the respective molecule
(iv) determination of molar ratio of the compounds raken
(v) `1 : 2`
