Chemistry Question on Expressing Concentration of Solutions
The conductivity of a solution of complex with formula CoCl3(NH3)4 corresponds to 1 : 1 electrolyte, then the primary valency of central metal ion is ______.
Answer
In 1 : 1 type of electrolyte the ions have +1 and -1 charge on them
∴ Possible compound is -> [Co(NH3)4Cl2]+Cl-
Oxidation state of central atom represents the total number of primary valency
∴ Primary valency will be 3.
