Abstract

Abstract The shape and the size of barium sulfate precipitate prepared within the range of the total concentrations from 1.0000 to 0.0001 m were observed by an electron microscope. The particles were observed to precipitate in various forms (spherical, spindle, diamond and rectangular) in response to the total concentration of barium sulfate. It was confirmed that the precipitation law advocated by von Weimarn was still substantiated so far as the particles of the same shape were concerned.
