the copper sulfate reacts and changes colour
Why does the colour of copper sulphate solution change when an iron nail is dipped in it? When an iron nail is placed in a copper sulphate solution, iron displaces copper from copper sulphate solution forming iron sulphate, which is green in colour. Therefore, the blue colour of copper sulphate solution fades and green colour appears.
Sodium Chloride is neutral. And Phenolphthalein is colourless when neutral.
by using separating funnel
When an iron nail is dipped in the copper sulfate solution then iron displaces copper from the copper sulfate because iron is more reactive than copper.

The dihydrated salt is blue-green.
A cooled saturated solution of copper chloride will precipitate crystals of copper chloride.
A solution of copper chloride should be electrolyzed.
Copper is corroded in a sodium chloride solution; CuCl2 is formed.
