Take 4, 500 ml of conical flasks, number them as 1,2,3,4. 2. Weigh 50g of sand to each of the 4 conical flasks. 3. Accurately weigh 5g of pure Na2CO3 and put it in each conical flask. Now each conical flask has 50g of sand and 5g of Na2CO3, Mix well. 4. Add 15 ml of water to each conical flask to wet the solid. 5. Measure and pour 50 ml, 100 ml, 150 ml, and 200 ml of water into the conical flasks 1,2,3,4 respectively. From procedures above in leaching experiment, we are using sodium carbonate as a solvent. A. True B. False
