Solution - homogenous mixture of 2 or more substances Solute - What is being dissolved Solvent - What is doing the dissolving Saturated - The solution is at the maximum amount of solute Supersaturated - There is more solute dissolved than usually allowed because of a change in the pressure or temperature during dissolution Unsaturated - The solution does not have the maximum amount of solute for its volume of solvent ppm (parts per million) - grams of solute/ grams of solution x 10^6 ppb (parts per billion) - grams of solute/ grams of solution x 10^9 Molarity - mol solute/L solution Beers Law - Absorbance = molar absorptivity x path length x concentration of absorber A1/C1 = A2/C2 - absorbance of solution 1 divided by concentration 1 is equal to the absorbance of solution 2 divided by concentration of solution 2 Dilutions - The process of adding a solvent to a solution to decrease the concentration dilution equation - M1V1=M2V2 M1V1=M2V2 - Formula used to determine how to create a solution of desired concentration from a stock solution of known Molarity and volume
