A very dilute acidic solution of Cd^(2+)...

A very dilute acidic solution of `Cd^(2+)&Ni^(2+)` gives only yelllwo ppt. of CdS on passing `H_(2)S`, this is due to:

A

solubility product `(K_(sp))` of CdS is more than that of NiS.

B

Solubility product `(K_(sp))` of CdS is less than that of NiS.

C

`Cd^(2+)` belong to II B group while `Ni^(2+)` belongs to `IV`th group

D

CdS is insoluble in yellow ammonium sulphide (YAS).

Text Solution

Verified by Experts

The correct Answer is:
B

Basic radicals are classified on the basic of increasing order of `K_(sp).Cd^(2+)` in II group while `Ni^(2-)` in IV group.

pH calculation upon dilute of strong acid solution is generally done by equating n_(H) in original solution & diluted solution.However . If strong acid solution is very dilute then H^(+) from water are also to be considered take log3.7=0.568 and answer the following questions. A 1 litre solution of pH=6 (solution of a strong acid) is added to the 7//3 litres of water.What is the pH of resulting solution? Neglect the common ion effect on H_(2)O .
