Which of the following statement is correct ?

Options

A. `Fe^(+3)`give a deep green ppt. on adding `K_(4)[Fe(CN)_(6)]` solution
B. On boiling a solution having `K^(+), Ca^(2+)` and `HCO_(3)^(-)` ions, we get a precipitate of `K_(2) [Ca(CO_(3))_(2)]`
C. Manganese salts gives a violet borax bead test in reducing flame
D. From a mixed precipitate of AgCl and Agl, ammonia solution dissolves only AgCl

Answer

D

Explanation

AgCl forms a soluble complex with `NH_(3)` but Agl does not form any complex.
`AgCl + 2NH_(3) rarr underset("Soluble complex")([Ag (NH_(3))_(2)]Cl)`
