A compound is made by mixing cobalt (III) nitrite and potassium nitrite solutions in the ratio of 1:3. The aqueous solution of the compound showed 4 particles per molecules whereas molar conductivity reveals the presence of six electrical charges. The formula of the compound is :

`Co(NO_(2))_(3).2KNO_(2)`

`Co(NO_(2))_(3).3KNO_(2)`

`K_(3)[CO(NO_(2))_(6)]`

`Ni[(CO)_(4)]`

Text Solution

Verified by Experts

The correct Answer is:

`K_(3)[Co(NO_(2))_(6)]to3K^(+)+[Co(NO_(2))_(6)]^(3-)`
