Sulfides are insoluble unless combined with Li, Na, K, Rb, Cs, and NH4.

So, Na2S is soluble, and CuS is insoluble.

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.


Is sugar more soluble than copper sulphate?

Yes, sugar is more soluble than copper sulfate in water. Sugar dissolves readily in water due to its molecular structure, while copper sulfate requires more energy and agitation to dissolve completely.


Is atropine hydrogen sulphate water soluble?

Yes, atropine hydrogen sulphate is water soluble. It dissolves in water to form a clear solution.


How do you separate copper sulfate and sulfur?

You can separate copper sulfate and sulfur by heating the mixture. Sulfur has a lower melting point than copper sulfate, so it will melt and can be separated by filtering while copper sulfate remains solid.


What is The name of the copper sulphate after being heated?

Copper Sulphate usually is found in a hydrated form (i.e., water molecules are incorporated into the crystals.) Pure copper sulphate is a pale, greenish gray color. The familiar blue color only occurs in hydrates of copper sulphate (i.e., in crystals that incorporate H20 molecules). Heating the blue crystals can drive off the water. It's still called copper sulphate after you do that. For substances like copper sulphate that naturally attract water, the adjective, anhydrous often is used to describe the pure (water free) state. If you heat copper sulphate to a temperature of 650C, it will decompose into something else. http://en.wikipedia.org/wiki/Copper_sulphate

Does copper sulphate dissolve in oil?

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


How soluble is Copper Sulphate?

highly water soluble, i.e it dissolves very easily in water.


Is copper oxide soluble?

copper sulphate is soluble in water - take the reaction to form blue crystals (sulphuric acid + copper carbonate) - once the water is evaporated off blue crystals are left. And if the water is evaporated off still the crystals turn white! so it must be.


Are copper sulphate crystals soluble?

Yes, in a saturated copper sulfate solution.


What happens when copper sulphate is dissolved in water?

When copper sulfate is dissolved in water, it dissociates into copper ions (Cu2+) and sulfate ions (SO4 2-). This forms a blue-colored solution due to the presence of copper ions in the water. The solution can conduct electricity due to the presence of free ions.

Is copper sulphate soluble in coconut oil?

Yes, Copper Sulfate is soluble in coconut oil.


What would happen if you added copper sulphate to water at room temperature?

Copper sulfate is soluble in water and dissociated in ions (Cu2)+ and (SO4)2-.


What happens when water and white copper sulphate mix together?

When water and white copper sulfate mix together, the copper sulfate will dissolve in the water, resulting in a blue solution. This is because copper sulfate is a water-soluble compound.


Is sulphate soluble?
