UNIT 4 Solutions and Solubility Chapter 8 Solutions and Concentration Types of Solutions The simplest solutions contain 2 substances: 1. SOLVENT o any substance that has another substance dissolved in it. o The substance present in the largest amount (by volume, mass, or moles) 2. SOLUTE o The substance dissolved in the solvent. When solute dissolves in a solvent, it is a physical interaction and the substances can be separated by physical means (melting or boiling points). Solutions are HOMOGENEOUS mixtures and can be gases, liquids, or solids. Steel Carbon + Iron Koolaid Sugar + Water Air Nitrogen + Oxygen + Carbon Dioxide Most common solutions are liquid The most common of these are AQUEOUS SOLUTIONS where WATER is the SOLVENT. Many substances dissolve easily in any proportion. These substances are said to be MISCIBLE with each other. Ex. Water and Ethanol
