Permanganate (VII) ion, `MnO_(4)^(-)` oxidises `I^(-)` ion to `I_(2)`

1.	Permanganate (VII) ion, `MnO_(4)^(-)` oxidises `I^(-)` ion to `I_(2)` and gives manganese (IV) oxide `MnO_(2)` in basic medium. The skeletal ionic equation is given as `pMnO_(4(aq))^(-)+qI_((aq))^(-)+x H_(2)O_((l)) rarr rMnO_(2(s))+sI_(2(s))+yOH_((aq))^(-)` The values of p, q, r and s areA. `{:(,p,q,r,s),(,1,2,8,4):}`B. `{:(,p,q,r,s),(,2,6,2,3):}`C. `{:(,p,q,r,s),(,2,4,2,8):}`D. `{:(,p,q,r,s),(,1,4,8,2):}`
Answer» Correct Answer - B `2MnO_(4(aq))^(-)+6I_((aq))^(-)+4H_(2)O_((l))rarr 2 MnO_(2(s))+3I_(2(s))+8OH_((aq))^(-)`
