Calcium Sulfate, CaSO4, is insoluble. Thus, this compound forms a precipitate. Sulfates are usually soluble except when they are reacted with Silver (Ag), Mercury (Hg), Lead (Pb), Calcium (Ca), Strontium (Sr), and Barium (Ba). This should help. :)

Does copper sulphate dissolve in oil?

No. All metal sulphate are soluble in water, except barium sulphate, calcium sulphate and lead sulphate.


How do you separate copper sulphate from calcium carbonate?

To separate copper sulfate from calcium carbonate, you can dissolve the mixture in water. Copper sulfate is soluble in water, while calcium carbonate is not. This solubility difference allows you to filter out the solid calcium carbonate and then evaporate the water to obtain copper sulfate crystals.


What a precipitation?

precipitate means done with very great haste and without due deliberation; separate as a fine suspension of solid particles When two chemicals in solution react to form a compound which is not soluble in water, the insoluble chemical appears as small undissolved particles = a precipitate. Sodium sulphate and calcium nitrate are both soluble forming clear solutions in water. Mix the solutions and they switch around to sodium nitrate (soluble) plus calcium sulphate (insoluble) and you get a milky looking suspension of calcium sulphate which is the precipitate.

Is sulphate soluble?

No. Silver sulphate is insoluble in water.


Why only magnisium sulphate and calcium sulphate cause hardness of water not sodium sulphate?

Magnesium sulfate and calcium sulfate cause hardness in water because they are slightly soluble in water, leading to the presence of excess ions in the water. Sodium sulfate, on the other hand, is highly soluble and does not produce excess ions that contribute to water hardness.
