EFFECT OF PULVERIZING Procedure: Weigh out two 2 g portions of coarse crystals. Grind one portion to a fine powder, but do not pound the crystals. Place the finely ground crystals into one baby-food jar and the coarse crystals into a second baby-food jar. Now add 25 mL of water to each baby-food jar. Put lids on both jars. Simultaneously agitate the two jars with a swirling motion. Observe the time required for complete solution in each jar. Observations & Analysis: Record of dissolving times. crystal = pulverized = Why are the dissolving rates different?
