Question

Ionisable chloride ions in $CoC{l}_5\cdot 4N{H}_3$ are_____.

Answer 1

Ionisable chloride ions in $CoC{l}_5\cdot 4N{H}_3$ are 3.
2 chlorine atoms are present in the coordination sphere and 3 chlorine atoms are present in ionization sphere.
$CoC{l}_5\cdot 4N{H}_3\rightleftharpoons \left[Co\right(N{H}_3{)}_{4}C{l}_2{]}^{3+}+3C{l}^{-}$
