Document Summary
10/3/16: chemist who propose the ionic theory of solutions to account for conductivity of pure water being electrically conducted by dissolving certain substances. Certain substances produce freely moving ions when they dissolve in water, and these ions conduct an electric current in an aqueous solution. Ex: when dissolving nacl, the na+ and cl= ions are freely moving around in the water and this movement of electrons constitute the electric current. Pure water is a nonconductor of electricity but has the ability to dissolve various substance. Section 1 ionic theory of solutions and solubility rules. Electrolytes and nonelectrolytes: electrolyte: a substance that dissolves in water to give an electrically conduction solution. Ex: nacl or table salt, is an example of an electrolyte. When most ionic substances dissolve in water, ions that were in fixed sites in the crystalline solid go into the surrounding aqueous solution, where they are free to move about.
