Answer to Question #158117 in General Chemistry for Tania

Question

Explain how the von Weimarn ratio can effect the particle sizes of barium sulfate precipitate.

Answer 1

According to Von Weimarn, the mean magnitude of the individual crystals of precipitates will progressively decrease with progressively increasing concentrations of the reacting solutions providing the process of direct crystallization is complete.

Therefore, the higher the concentration of barium sulfate solution, the lower the mean magnitude of barium sulfate crystals.
