SPREADING Of LIQUIDS ON MERCURY SURFACE

The laws of spreading of water containing traces of HCl, H₂SO₄, HNO₃,H₃PO₄, NaCl, KCl, RbCI, CsCl, and colloidal graphite solution irradiated by X-rays have been studied on Hg surface, and the number of H⁺ or alkali ions necessary to produce a critical area of 1cm². has been evaluated. The nature of the spreading forces the significance of Harkin's coefficient controlling the spreading phenomenon have also been discussed.
