Solutions and Solubility http://students.millikin.edu/~acs/HTML/IMG_0020.jpg

Solute: The substance that is dissolved. Solution: A mixture that appears to be a single substance but is composed of particles of two or more substances that are evenly distributed amongst each other. Solute: The substance that is dissolved. Example - salt Solvent: The substance doing the dissolving. Example - water

Zn and Cu Types of Solutions Hg, Ag, Cu

What affects Solubility? Remember the Solubility of a Life Saver Lab Temperature Surface area: Crushing Stirring Type of solvent Combination ????

Solubility, Temperature, Type of Solute Dilute solution vs. Concentrated solution: A qualitative way to compare solutions based on comparison of amount of solute. Often determined by viewing the color of the solution. The amount of solute dissolved in not specified.

Saturated vs. Unsaturated Solutions: A solution that contains all the solute it can hold at a given temperature is saturated. Precipitate forms if more solute is added.

Solubility, Temperature, Type of Solute Solubility: The amount of a solute needed to make a saturated solution using a given amount of solvent at a certain temperature. Example: The number of grams of NaCl that is needed to make a saturated solution with 100 ml of water at 200C is 39 grams. Concentration of a solution: The amount of solute dissolved in a given amount of solvent. Expressed in grams/ml.
