Because Copper does not have a high solubility rate.
Wash the mixture with water and separate the solid from the liquid, for example, by filtration. The sodium chloride will dissolve in the wash water, while the copper is left behind.
Copper Sulphate will dissolve better in warmer water, it will dissolve both faster and it will be possible do dissolve a greater mass of the Copper Sulphate.
Sodium Bromide is a stable salt. It will dissolve in water.
of couse~ can.... even 2ml of water dissolve in 4.0 grams of copper sulfate.
Copper metal itself does not react with sodium hydroxide. But when NaOH is added to a solution of copper ions, it would form a light blue precipitate, which is copper(II) hydroxide, and will NOT dissolve with the excess alkali.
Most metals (like Steel, Aluminium, Copper etc.) do not dissolve in water, however there are some (like Sodium) that will.
Wash the mixture with water and separate the solid from the liquid, for example, by filtration. The sodium chloride will dissolve in the wash water, while the copper is left behind.
Copper Sulphate will dissolve better in warmer water, it will dissolve both faster and it will be possible do dissolve a greater mass of the Copper Sulphate.
Put the mixture in a beaker then add some water. Stir until the sodium chloride is completely dissolved. Filter the water to get copper oxide as your residue. Then strongly heat the water till it evaporates, to form crystals of sodium chloride.
water
Water doesn't dissolve sodium, water react violently with sodium:2 Na + 2 H2O = 2 NaOH + H2
Copper is a metal element. It does not dissolve in water.
Na2CrO4 will dissolve in water as will all sodium compounds.
Sodium can dissolve. Citric acid can also dissolve into water.
because it cool
Sodium doesn't dissolve in water, it reacts with water to form sodium hydroxide and hydrogen: sodium + water ----> sodium hydroxide + hydrogen
hot water
