Chapter 17: Properties of Solutions Types of Solutions Solution: A homogeneous mixture. Solutions are made up of at least two parts Solvent: The most abundant component of a solution. Solute: A dissolved substance. 2 State of Solution State of Solvent State of Solute Example Gas Gas Gas Air Natural gas Liquid Liquid Liquid Antifreeze Tequila Liquid Liquid Gas Soda water Liquid Liquid Solid Sea water Sugar water Solid Solid Solid Alloys (Steel or brass) Solid Solid Gas Hydrogen in platinum

Chapter 17: Properties of Solutions Solubility Cation and H 2 O Anion and H 2 O Hydration: The reaction of a substance with water. 4 Note: For molecules, the extent of hydration increases as polarity increases. Note: For ions, the extent of hydration increases as charge density (charge per volume) increase. In general, the smaller the size, the larger the charge density and the larger the charge, the higher the charge density.

Unformatted text preview: Chapter 17: Properties of Solutions Student Question Solubility Which one of the following substances would be the most soluble in CCl 4 ? a) CH 3 CH 2 OH b) C 10 H 22 c) H 2 O d) NaCl e) NH 3 5 Chapter 17: Properties of Solutions Solubility Saturated Solution: A solution that holds the maximum amount of solute. Unsaturated Solution: A solution that holds less than the maximum amount of solute. Supersaturated Solution: A solution that holds more than the maximum amount of solute. If a solutions is supersaturated any small disturbance can cause the solute to recrystallize 6 Chapter 17: Properties of Solutions Solubility The lines show the saturation level of a solution at a given temperature. If a solution has a solubility that results in a point above the line, then the solution is considered to be supersaturated. However, if a solution has a solubility that results in a point under the line, then the solution is considered unsaturated. 7 Chapter 17: Properties of Solutions Solubility 8...
