The conductivity of a solution of complex with formula $\mathrm{CoCl}_{3}\left(\mathrm{NH}_{3}\right)_{4}$ corresponds to 1 : 1 electrolyte, then the primary valency of central metal ion is __________.
Answer (integer)
3
Solution
In 1: 1 type of electrolyte the ions have $+1$ and $-1$ charge on them <br/><br/>
$\therefore$ Possible compound is $\rightarrow\left[\mathrm{Co}\left(\mathrm{NH}_{3}\right)_{4} \mathrm{Cl}_{2}\right]^{+} \mathrm{Cl}^{-}$
<br/><br/>Oxidation state of central atom represents the total number of primary valency
<br/><br/>
$\therefore$ Primary valency will be 3 .
