consumers Delving Deeper into the Essentials 1 Defining the Basics What are mixtures Mixtures are combinations of two or more substances that are physically combined but not chemically bonded Each component retains its individual properties What are solutions Solutions are a special type of mixture where one substance the solute is dissolved evenly throughout another substance the solvent They are homogeneous meaning their composition is uniform throughout Differentiating between Homogeneous and Heterogeneous Mixtures Homogeneous mixtures Have a uniform composition throughout Examples include saltwater air and sugar dissolved in water Heterogeneous mixtures Have a nonuniform composition with different components easily distinguishable Examples include sand and water oil and water and a salad 3 2 Understanding Solutions Solute and Solvent Solute The substance being dissolved Solvent The substance doing the dissolving Factors Affecting Solubility Temperature Solubility usually increases with temperature Pressure Pressure affects the solubility of gases in liquids Nature of the solute and solvent Like dissolves like Polar solvents dissolve polar solutes and nonpolar solvents dissolve nonpolar solutes Concentration The amount of solute dissolved in a given amount of solvent or solution It can be expressed in various units such as molarity molality percent by mass and parts per million 3 Separation Techniques Decantation Separating a liquid from a solid by carefully pouring off the liquid Filtration Separating a solid from a liquid by passing the mixture through a filter Evaporation Separating a dissolved solid from a liquid by heating the solution and allowing the solvent to evaporate Distillation Separating a liquid from a mixture of liquids with different boiling points Chromatography Separating components of a mixture based on their different affinities for a stationary phase and a mobile phase 4 The Impact of Mixtures and Solutions on Our World Everyday
