As a result, the solvent molecules ____________ with the ______________ of the sugar crystals more frequently and with more force. 16.1

Slide 5 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Solution Formation Particle Size and Solution Formation A spoonful of granulated sugar dissolves more quickly than a sugar cube because the _____________ ____________ in granulated sugar expose a much greater ___________ ____________ to the colliding water molecules. 16.1

Slide 6 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Solubility A _______________ solution contains the ________________ amount of solute for a given quantity of ___________ at a given _____________ and _____________. An _______________ solution contains less solute than a _____________ solution at a given temperature and pressure. 16.1

Slide 7 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Solubility In a saturated solution, the __________ of ____________ equals the _______ of ____________, so the total amount of dissolved solute remains _______________. 16.1

Slide 8 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Solubility The ________________ of a substance is the amount of solute that dissolves in a given quantity of a solvent at a specified temperature and pressure to produce a saturated solution. Solubility is often expressed in ____________ of _____________ per 100 g of ______________. 16.1

Slide 9 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Solubility Some liquids combine in all proportions, while others don’t mix at all. Two liquids are ____________ if they dissolve in each other in ___ proportions. Two liquids are _______________ if they are ______________ in each other. 16.1

© Copyright Pearson Prentice Hall Properties of Solutions > Slide 11 of 39 Factors Affecting Solubility _______________ affects the solubility of solid, liquid, and gaseous solutes in a solvent; both _____________ and ________________ affect the solubility of gaseous solutes. 16.1

Slide 12 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Factors Affecting Solubility Temperature The solubility of most solid substances ______________ as the temperature of the solvent ________________. The solubilities of most gases are _____________ in _________ water than in ___________. 16.1

Slide 13 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Factors Affecting Solubility The __________ deposits around ______ springs result from the cooling of the ____, ___________ solution of minerals emerging from the spring. 16.1

Slide 14 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Factors Affecting Solubility 16.1

Slide 15 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Factors Affecting Solubility A __________________ solution contains _____________ solute than it can theoretically hold at a given temperature. The crystallization of a supersaturated solution can be initiated if a very __________ ___________, called a seed crystal, of the solute is added. 16.1

Slide 16 of 39 © Copyright Pearson Prentice Hall Properties of Solutions > Factors Affecting Solubility A supersaturated solution is clear before a seed crystal is added Crystals begin to form in the solution immediately after the addition of a seed crystal. Excess solute crystallizes rapidly.
