Balance the following equation : Kl + H_(2)SO_(4) + H_(2)O_(2) to K_(2)SO_(4) + I_(2) + H_(2)O |
|
Answer» Solution :The given equation can be split into following probable partial equations. `H_(2)O_(2) to H_(2)O + O`………….(i) `Kl + H_(2)O + O to KOH + I_(2)`…….(ii) `KOH + H_(2)SO_(4) to K_(2)SO_(4) +H_(2)O`………(iii) On balancing these partial equations by hit and trial method, we GET: `H_(2)O_(2) to H_(2)O + O`........(iv) `2Kl + H_(2)O + O to 2KOH + I_(2)`......(v) `2KOH + H_(2)SO_(4) to K_(2)SO_(4) + 2H_(2)O`.......(vi) The INTERMEDIATE SPECIES O and KOH can be cancelled simply by ADDING these equations. `H_(2)O_(2) to H_(2)O + O` `2Kl + H_(2)O + O to 2KOH + I_(2)` `overset(2KOH + H_(2)SO_(4) to K_(2)SO_(4) + 2H_(2)O)underset(2Kl + H_(2)SO_(4) +H_(2)O_(2) to K_(2)SO_(4) + I_(2) + 2H_(2)O) (------------)` |
