Name :
two colourless metal ions.

Name : two coloured metal ions.

Name : a coloured metallic oxide which dissolves in alkalis to yield colourless solutions.

The flame colours of metal ions are due to

A metal whose alloy finds use in the construction of air crafts in the powdered form is added to sodium hydroxide solution. A colourless gas was evolved. After the reaction was over, the solution was colourless Name the salt present in the colourless solution.

Name the type of isomerism when ambidentate ligands are attched to central metal ion. Give two examples of ambidentate ligands.

A solution of a metal ion when treated with KI gives a red precipitate which dissolves in excess KI to give a colourless solution. Moreover, the solution of metal ion on treatment with a solution of cobalt (II) thiocyanate gives rise to a deep blue crystalline precipitate. The metal ion is

Give examples and explain with equations: (a)Two colourless solution give a black precipitate on mixing. (b)Two colourless solutions give a red precipitate on mixing, soluble in excess of one of them. ( c)Two colourless solutions give a white precipitate on mixing, soluble in ammonium hydroxide. (d)Two colourless solutions give a yellow precipitate on mixing.

Why are the alkali metal ions colourless and diamagnetic ?

A solution of a metal ion when treated with KI gives a red precipitate which dissolves in excess KI to give a colourless solution.Moreover, the solution of metal ion on treatment with a solution of cobalt (II) thiocyanate gives rise to a deep blue crystalline precipitate.The metal ion is:

A solution of a metal ion when treated with KI solution gives a red precipitate which dissolves in excess of KI solution to give a colourless solution. Moreover, the solution of the same metal ion on treatment with the solution of cobalt (II) thiocyanate gives rise to a deep blue crystalline precipitate. The metal ion is
