How would you separate copper chloride and sodium chloride?
By pouring ethanol into the mixture of the two crystalline substances, the copper chloride will freely dissolve in the ethanol whilst sodium chloride will not (mostly).
How would you separate a mixture of sodium chloride and copper II oxide?
Answer: Add water to the mixture of sodium chloride and copper(ii)oxide, sodium chloride will dissolve while copper(ii)oxide does not. Filter and heat the filtrate to dryness to obtain sodium chloride.
What is the best method to separate sodium chloride?
A mixture of sodium chloride and sand in water can be separated by the process of filtration and then by the process of distillation.
What happens when you mix sodium chloride and copper sulfate?
Explanation: Aqueous sodium chloride, NaCl , will not react with aqueous copper(II) sulfate, CuSO4 , because the two potential products are soluble in aqueous solution. This means that the reaction does not produce an insoluble solid that precipitates out of solution.
How do u separate a mixture of copper sulphate salt and water?
Separating solids from liquids – evaporation Evaporation is used to separate a soluble solid from a liquid. For example, copper sulfate is soluble in water – its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid copper sulfate crystals behind.
Is Copper II oxide soluble in water?
Copper(II) oxide
| Names | |
|---|---|

| Solubility in water | insoluble |
| Solubility | soluble in ammonium chloride, potassium cyanide insoluble in alcohol, ammonium carbonate |
| Band gap | 1.2 eV |
Which methods could be used to prepare copper II chloride?
Preparation. Copper(II) chloride is prepared commercially by the action of chlorination of copper. Copper at red heat (300-400°C) combines directly with chlorine gas, giving (molten) copper (II) chloride. The reaction is very exothermic.
Can copper chloride be separated?
The technique of extraction is used to separate an aqueous solution of copper (II) chloride and iodine. Aqueous solutions of CuCl2 are turquoise. Iodine in water is yellow, and when added to the copper solution the result is a green solution.
What methods can be used to prepare copper chloride?
How can we separate sodium chloride from water?
- Sodium chloride from its solution in water is done by Evaporation method.
- Ammonium chloride from a mixture containing sodium chloride and ammonium chloride is done by Sublimation.
- Mixture of oil and water is done by separating funnels.
- Fine mud particles suspended in water are done by decantation and filtration.
Which two substances can be separated by sublimation?
Mixture of camphor and common salt can be separated by sublimation.
