An ammoniacal metal salt solution gives a brilliant red precipitate on addition of dimethylglyoxime. The metal ion is :Cu2+Ni2+Fe2+Co2+
Question
Solution 1
The metal ion is Ni2+. This is because dimethylglyoxime reacts with nickel ions in an ammoniacal solution to form a brilliant red precipitate. This is a specific test for nickel ions. Other metal ions like Cu2+, Fe2+, Co2+ do not give this red precipitate with dimethylglyoxime. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study problem.
