1 V. Concentrations of Solutions – household: bleach – 5% to 6% NaOCl (aq); H 2 O 2 –3% A. Molarity – a term that quantifies concentration 1. 2. Pr. Ex. 4.11, BLB p147 Calculate the molarity of a solution made by dissolving 5.00 g of glucose, C 6 H 12 O 6 , in sufficient water to form exactly 100 mL of solution. M = moles of solute L of solution B. Expressing the Concentration of an Electrolyte – when ionic compounds dissolve, concentration of ions in solution depends on chemical formula. 1. 2. 3. Pr. Ex. 4.12, BLB p147 What is the molar concentration of K + ions in a 0.015 M solution of potassium carbonate? 4.69 Indicate the concentration of each ion or molecule present in the following solutions: a) 0.22 M NaOH b) 0.16 M CaBr 2 c) 0.15 M CH 3 OH d) a mixture of 40.0 mL of 0.15 M KClO 3 and 35.0 mL of 0.22 M Na 2 SO 4 . Assume the volumes are additive. d) a mixture of 40.0 mL of 0.15 M KClO 3 and 35.0 mL of 0.22 M Na 2 SO 4 . Assume the volumes are additive. Which will have the highest
