Document Summary

Solution homogeneous mixture, components are uniformly intermingled. Solvent the substance present in the largest amount. Solutes other substance or substances in the mixture. Aqueous solution solutions with water as the solvent. To understand the process of dissolving and to learn why certain components dissolve in water. When ionic substance dissolve in water , the resulting solution conducts an electric current. Solutions contain ions that can move this is how the electric current is conducted. When a solid dissolves in water the ions are dispersed randomly throughout the. It"s soluble. solution each polar water molecule orients itself in a way to maximize its attraction with the solvent/solutes. When an ionic substance (ie. salt, nacl) dissolves in water, it breaks up into individual cations (positive ions) and anions (negative ions) which are dispersed in the water. Water also dissolves many nonionic substances (ex. sugar)
