Potassium sulfate forms a spiral structure when dissolved in solution

Macrokinetics of Complex Physicochemical Phenomena


Studies on the formation of spiral structures are always of interest to researchers. When potassium sulfate is heated in water and subjected to swirling in a beaker, the crystals formed a multi-arm spiral structure when allowed to settle. The spiral structure was either clockwise or anti-clockwise depending on the rotation of the swirl. The spiral formation requires heat to maintain integrity of the structure. The multi-arm spiral structure of potassium sulfate was stable if left undisturbed at room temperature.
