- BAmmoniacal cobalt chloride solution
- CAmmoniacal manganese sulphate solution
- DMagenta solution decolourised with chlorine
✓
Answer
Correct option: A.
Magenta colour solution decolourised with sulphurous acid
a
Schiff's Reagent is an aqueous solution of magenta or pink coloured Rosaniline Hydrochloride which gets decolourised when $SO _2$ is passed through it,That's why used as a distinction test for aldehydes.
