Statement -1 :An original solution containing excess of `Ni^(2+)` ions gives a yellow coloured solution with potassium cyanide solution.
Statement-2 :A solution of `Ni^(2+)` ions gives red precipitate with dimethylglyoxime solution just made alkaline with ammonia.

Options

A. Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1.
B. Statement-1 is True, Statement-2- is True, Statement-2 is NOT a correct explanation for Statement-13
C. Statement-1 is True, Statement-2 is False
D. Statement-1 is False, Statement-2 is True

Answer

B

Explanation

`Ni^(2+)+2CN^(-) rarr Ni(CN)_(2)darr overset(CN^(-))rarr underset(("Yellow solution"))([Ni(CN)_(4)]^(2-))`
`Ni^(2+)+DMG rarr underset(("Red ppt"))(Ni(DMG)_(2)darr`
