Question 6
In this conservation-of-mass experiment, 100 ml of calcium chloride solution is placed in a conical flask and 20 ml of sodium sulfate solution in a test tube inside it. The flask is stoppered. The entire sealed set-up is weighed, then the test tube is tipped to mix the solutions without opening the flask. The entire set-up is weighed again after reaction. Wear safety goggles and gloves.
