## Abstract A new polymorph of sodium chondroitin‐4‐sulfate has been crystallized from an ethanolic aqueous solution at low pH. The crystallized spherulite specimens give considerably sharper x‐ray diffraction lines. The unit cell of the new polymorph is rectangular with dimensions (Å) __a__ = 16.0

## Abstract The growth and dissolution kinetics of potassium sulfate was studied based on single crystal measurements. The growth rate is correlated to the supersaturation with power low equation. At all the temperatures studied, the growth rate order lies in the range of 1‐1.5 with the surface int
