3. Concentrations: amount of solute present in a given mass or volume of solution. % by Mass – % solute = mass of solute/mass of solution x 100% A 10% glucose solution by mass contains 10.0 grams of glucose in 100 grams of solution. (90 grams of water and 10 grams of glucose)

6. Molarity = number of moles of solute/number of liters of solution If 39.10 grams of potassium were added to 1.0 L of water, what would the molarity of this solution be? If approximately 11.5 grams were added to 1.0 liter of water, what would the molarity of this solution be?

9. Supersaturated Solution

12. Ionization: acids or any molecular compound separates in solution to form ions. Dissociation: ionic compounds separates into its ions in solution Strong Acids: ionize close to 100% into H+ ions. (HCl; HNO 3 ; H 2 SO 4 ) Weak Acids: ionize less than 5% into ions (Acetic Acid)

14. Strong (soluble) bases: dissociate completely in aqueous solution (NaOH; LiOH; KOH) Weak Bases: ionize slightly in aqueous solutions (NH 3 )

15. Salt: contains a cation (other than H+) and an anion (other than OH-) Salts are formed when acids react with bases.
