Why cromate can easily be converted to dicromate?
Chromate (CrO4^2-) can easily be converted to dichromate (Cr2O7^2-) due to the change in pH of the solution. In acidic conditions, chromate ions react with hydrogen ions (H+) to form dichromate ions. This equilibrium is influenced by the concentration of hydrogen ions, which shifts the balance toward dichromate formation in lower pH environments. Thus, the conversion is a simple acid-base reaction dependent on the acidity of the solution.
What are the developing reactions that allow the identification of NI2 plus and Cu2 plus?
Nickel(II) ions (Ni²⁺) can be identified using a reaction with dimethylglyoxime, which produces a bright red precipitate of nickel dimethylglyoxime complex. Copper(II) ions (Cu²⁺) can be identified through the formation of a blue complex when reacted with ammonia, resulting in a deep blue solution of tetraamminecopper(II) complex. Both reactions serve as qualitative tests to differentiate these metal ions in solution.
