Question

4. Name basic radicals which are absent if given salt is white?
Ans.​

Answer 1

Answer:

cu+2,Fe+2,Fe+3,cr+3,Ni+2,Co+2,Mn+2

Answer 2

Copper - $Cu^+^2$ and Iron (II) - $Fe^+^2$

Explanation:

• The identification of the cation and anion of inorganic salt is known as Salt analysis or qualitative inorganic analysis
• This is done by performing a series of experiment in a systematic manner and by different observations like color, odor, and smell, etc we confirm the absence or presence of cations and anions that helps in identification of salts

Basic radicals which are absent if given salt is white are mentioned below -

1. Copper - $Cu^+^2$
2. Iron (II) - $Fe^+^2$
3. Iron (III) - $Fe^+^3$
4. Cobalt - $Co^+^2$
5. Nickel - $Ni^+^2$
