Question

theory and figure for separate calcium carbonate from mixture of sand and calcium carbonate​

Answer 1

Answer:

After mixing calcium carbonate and salt with water, how were you able to separate out the calcium carbonate and salt from the water? [Calcium carbonate can be separated by filtration; sodium chloride solution can be separated by evaporation.]

Answer 2

Theory and figure for separate calcium carbonate from mixture of sand and calcium carbonate​

• Sands are tiny solids, whereas rocks are larger. As a result, handpicking can readily separate them. Sand and rocks can be easily separated from one another by hand-picking the rocks out of the mixture and setting them aside or in separate containers.
• While NaCl (Sodium chloride) is soluble in water, CaCO3 (Calcium carbonate) is not. NaCl dissolves in water when we add water to this combination. The solution is next filtered, and because CaCO3 is insoluble, it sticks to the filter paper's pores and separates from the NaCl solution.
• Filtration is used to separate calcium carbonate from a solution of calcium carbonate and water.
• While calcium carbonate is not soluble in water, sodium carbonate is. Add water to the mixture and whisk it thoroughly to thoroughly dissolve the sodium carbonate before separating it. Sand and water are combined to be filtered using filter paper (a filter with very fine pores). Because they are larger than water molecules, sand particles are held in place by the filter paper.
• Sieving can be used to separate sand from chalk. Take a sieve with larger pores than any of the two. If the sand particles are larger and the chalk powder is finer, the sand will stay in the sieve and the chalk powder will filter through.
