Terms to Know Solute – the substance being dissolved Solvent – the substance used to dissolve Solution = solute + solvent NaCl is the solute O2 in water is attracted to the Na p.724 H2 in water is attracted to Cl2 Water is the solvent

Types of Solutions Liquid-Liquid (ex: ammonia + water) Solid-Liquid (ex: Kool-Aid & sugar + water) Solid-Solid (ex: penny = copper + zinc) Gas-Gas (ex:diver’s tank = oxygen + nitrogen) Gas-Liquid (ex: soda = CO2 + water + syrup)

Rate (Speed) of Dissolving Solids and Liquids Energy (stir – sweet tea) Size (surface area – BC powder) Temperature (heat – cooking) Gases Pressure (ex: soda bottle, air freshner)

Nonpolar Solutions Oil & water Oil & vinegar (Italian salad dressing) Alcohol & iodine + Dry cleaning fluid Soap (dishwashing, hand, detergent)

Polar Solutions Anything with that mixes with water (lemonade, Sprite, etc) Anything with vitamins inside (orange juice, vegetables, etc)

Solubility & Concentration Def: the maximum amount of solute that can be dissolved in a given amount of solvent at a given temperature. Concentration: How much solute is in the solvent. Example: 2 cups of sugar in 2 quarts of Kool-Aid

Types of Solutions Unsaturated – can dissolve more solute in the amount of solvent (not enough) Saturated – has all of the solute for the amount of solvent (just right) Supersaturated – contains more solute than the amount of solvent can handle (too much)

Solubility Curve Used to figure out how much solute will dissolve at a given temperature on the graph p.720
