Question
How is stability of coordination compounds determined in aqueous solution?

Answer

The stability of coordination compound is measured in terms of stability constant.
Thus if we have a reaction of the type
$
\begin{array}{l}
M+4 L \rightleftharpoons M L_4 \\
\beta_4=\frac{\left[M L_4\right]}{[M][L]^4}
\end{array}
$
