Question

During the qualitative analysis of salt with cation y 2 + , addition of a reagent X to alkaline solution of the salt gives a bright red precipitate. The reagent X and the cation y 2 + present respectively are :

TestHub · Accepted Answer

During the qualitative analysis of salt with cation ${Ni}^{2 +}$ , addition of a reagent $Dimethylglyoxime$ to alkaline solution of the salt gives a bright red precipitate according to the following reaction. So, The reagent $(X)$ and the cation $(y^{2 +})$ respectively are Dimethylglyoxime and ${Ni}^{2 +}$

${Ni}^{2 +} + dmg \overset{Ammonical Solution}{\to} \underset{Red colur}{[Ni {(dmg)}_{2}]} ↓$ ,
