Aug 10, 2020  Understanding the conditions that favor particle growth is important when we design a gravimetric method of analysis. We define a solute’s relative supersaturation, RSS, as \[R S S=\frac{Q-S}{S} \label{8.12}\] where Q is the solute’s actual concentration and S is the solute’s concentration at equilibrium [Von Weimarn, P. P. Chem. Revs.
