  1. Concentration Units A solution is a homogenous mixture of 2 or more substances The solute is(are) the substance(s) present in the smaller amount(s)

  2. Solution Solvent Solute aqueous solutions of KMnO4 Concentration Units The solvent is the substance present in the larger amount H2O Soft drink (l) Sugar, CO2 Air (g) N2 O2, Ar, CH4 Pb Sn Soft Solder (s)

  3. Concentration Units A solution is a homogenous mixture of 2 or more substances The solute is(are) the substance(s) present in the smaller amount(s) The solvent is the substance present in the larger amount

  4. nonelectrolyte weak electrolyte strong electrolyte Concentration Units An electrolyte is a substance that, when dissolved in water, results in a solution that can conduct electricity. A nonelectrolyte is a substance that, when dissolved, results in a solution that does not conduct electricity.

  5. moles of solute liters of solution moles of solute m = mass of solvent (kg) M = Concentration Units Molarity(M) Molality(m)

  6. moles of solute M = molarity = liters of solution Concentration Units Solution Stoichiometry The concentration of a solution is the amount of solute present in a given quantity of solvent or solution.

  7. volume of KI solution moles KI grams KI 1 L 2.80 mol KI 166 g KI x x x 1000 mL 1 L soln 1 mol KI Concentration Units What mass of KI is required to make 500. mL of a 2.80 M KI solution? M KI M KI 500. mL = 232 g KI

  8. x 100% mass of solute x 100% = mass of solution mass of solute mass of solute + mass of solvent Concentration Units The concentration of a solution is the amount of solute present in a given quantity of solvent or solution. Percent by Mass % by mass =

  10. Dilution Add Solvent Moles of solute before dilution (i) Moles of solute after dilution (f) = = MfVf MiVi Concentration Units Dilution is the procedure for preparing a less concentrated solution from a more concentrated solution.

  11. 0.200 M x 0.0600 L = MfVf 4.00 M Vi = Mi Concentration Units How would you prepare 60.0 mL of 0.200 M HNO3 from a stock solution of 4.00 M HNO3? MiVi = MfVf Mi = 4.00 M Vi = ? L Mf = 0.200 M Vf = 0.0600 L = 0.00300 L = 3.00 mL Dilute 3.00 mL of acid with water to a total volume of 60.0 mL.
