QJEEM22Ch9dce: JEE Main 2022 Chemistry - Class 12 JEEM22Ch9dce Solution: The conductivity of a solution of complex with formula…

The conductivity of a solution of complex with formula CoCl3(NH3)4\mathrm{CoCl}_{3}\left(\mathrm{NH}_{3}\right)_{4} corresponds to 1 : 1 electrolyte, then the primary valency of central metal ion is __________.

Step-by-Step Verified Solution

In 1: 1 type of electrolyte the ions have +1+1 and −1-1 charge on them

∴\therefore Possible compound is →[Co(NH3)4Cl2]+Cl−\rightarrow\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{Cl}_{2}\right]^{+} \mathrm{Cl}^{-}

Oxidation state of central atom represents the total number of primary valency

∴\therefore Primary valency will be 3 .
