6. Unit 6 Solutions

7. IPC.6.E Relate the structure of water to its function as a solvent & investigate the properties of solutions & factors affecting gas & solid solubility, including nature of solute, temperature, pressure, pH & concentration. Do not need to write. This is what Unit 6 covers.

8. Solutions (p. 1; 1/5/16) Solutions are homogenous mixtures of > 2 substances. Can be solid Brass=> copper & zinc, & Sterling silver => 92.5% by mass of silver & 7.5% by mass of other metals, usually copper Can be gaseous (like air you breath) KEY WORDS ARE BOLDED &UNDERLINED

9. Parts of the Solution Solvent is the majority of the solution & the part of a solution that dissolves the solute. Example - water Solute is what is dissolved Example - Tea, Salt, Jello, Sugar, …

10. Solubility maximum amount of solute can be dissolved in a certain amount of a solvent at a given temperature Example: 35.7 g/ 100 mL Concentration % by volume of solute in solvent Concentrated - LARGE amount of solute in solvent Dilute – small amount of solute in solvent.

11. Solubility Solubility is determined by pressure & temperature. Dependent on substance on whether solubility increases or decreases as pressure &/or temperature increases or decreases.

12. Types of Solutions UnsaturatedSaturatedSuper Saturated Contains Less solute it can at a given temperature Contains ALL solute it can at given temperature Contains MORE solute it can at given temperature Solution is UNSTABLE
