Chapter 16-Solutions:
16.1- Properties of Solutions
<>the compositions of the solvent and the solute determine whether a substance will dissolve. Stirring (agitation), temperature, and the surface area of the dissolving particles determine how fast the substance will dissolve
<>--stirring speeds up the process b/c fresh solvent is continually brought into contact with the surface of the solute. --at higher temperature, the kinetic energy of water molecules is greater than at lower temperatures so they move faster ---the rate at which a solution dissolves also depends on the solute particles
<>saturated solution: contains the maximum amount of solute for a given quantity of solvent at a constant temp and pressure
<>solubility: the amount of solute that dissolves in a given quantity of a solvent at a specified tem and pressure to product a saturated solution
<>solubility is often expressed in grams of solute per 100g of solvent
<>unsaturated solution: contains less solute than a saturated solution at a given temp and pressure
<> ( ... )
