3-6 3 SOLUTIONS AND NAME SOLUTION CONCENTRATIONS 1415 Section Pre-Lab Assignment Experiment objectives A, B, and C require you to devise procedures for preparing a saturated aqueous solution of potassium sulfate, experimentally determining the density of this solution, and experimentally determining the mass percent of potassium sulfate in this solution. Your pre-lab assignment is to develop procedures for parts A, B, and C. You will then execute these procedures in lab. PREPARATION OF A SATURATED AQUEOUS POTASSIUM SULFATE SOLUTION Reminder: use a maximum of 75 mL of water. A. В. DENSITY OF SATURATED AQUEOUS POTASSIUM SULFATE SOLUTION C. MASS PERCENT OF POTASSIUM SULFATE IN A SATURATED POTASSIUM SULFATE SOLUTION
