The colour of KMnO(4) is due to...

The colour of `KMnO_(4)` is due to

A

Cations are coloured ions

B

Anions are coloured ions

C

Both correct

D

None is correct

Text Solution

Verified by Experts

The correct Answer is:
2
Alkali and alkali metal ions are as such colourless. Only they salts such as chromate,dichromate or permanganate are coloured due to the presence of coloured anions.

Assertion . The purple colour of KMnO_(4) is due to the charge transfer transition. Reason. The intense colour of most of the transition metal complexesis due to d-d transition,.

Potassium permanganate is prepared from the mineral pyrolusite, MnO_(2) . Its crystals have deep purple colour. It acts as an oxidizing agent in the neutral, alkaline as well as acidic medium. In acidic medium , it is used in volumetric analysis for estimation of ferrous salts, oxalates etc. The titrations are carried out in presence of H_(2)SO_(4) . However ,before using itas a titrant, it is first standized with standard oxalic acid solution or Mohr salt solution. In one of the experiments on titration , 13.4 g of dry pure sodium oxalate ( molar mass =134 g mol^(-1) ) was dissolved in 100mLof distilled water and then 100 mL of 2M H_(2)SO_(4) were added. The solution, was cooled to 25.30^(@) C . Now to this solution , 0.1 M KMnO_(4) solution was added till a very faint pink colour persisted. The purple colour of KMnO_(4) is due to
