Q. Which of the following complex will give white ppt. with $BaCl_2$ solution ?

Coordination Compounds

Solution:

$\left[ Cr \left( NH _3\right)_5 Cl \right] SO _4 \rightleftharpoons\left[ Cr \left( NH _3\right)_5 Cl \right]^{2+}+ SO _4^{2-}$
$SO _4^{2-}$ ions form precipitate with $BaCl _2$ solution
$SO _4^{2-}+ BaCl _2( aq ) \longrightarrow BaSO _4 \downarrow+2 Cl ^{-}( aq )$
