When you combine these substances, a metathesis reaction occurs. In this reaction, copper becomes bonded to hydroxide ions. Because copper hydroxide is insoluble, it precipitates out of solution.
Copper chloride + Sodium hydroxide --> Copper hydroxide + sodium chloride
Nothing
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
The products are Sodium Nitrate and Copper Hydroxide.
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
copper bromide + sodium Hydroxide = Copper Hydroxide + Sodium Bromide CuBr2 + 2NaOH = Cu (OH)2 + 2NaBr
Copper chloride + Sodium hydroxide --> Copper hydroxide + sodium chloride
When heat copper hydroxide and sodium Nitrate the pale blue precipitate change into black solid
Nothing
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
Metallic copper does not react with sodium hydroxide. But if sodium hydroxide is added into a solution of copper ions, it would form Copper(II) Hydroxide. It is a precipitate which is insoluble in water.
The products are Sodium Nitrate and Copper Hydroxide.
Sodium Bromide is produced from the reaction of Hydrobromic acid and sodium hydroxide.
it starts changing to white because the colour of the copper sulphate solution becomes whote during the process of evaporation
a big lump of mess i dont think so copper sulphate +sodium hydroxide = Na2So4 +Cu(OH)2 WHICH IS SODIUM SULPHATE AND COPPER HYDROXIDE
Sodium Bromide is a stable salt. It will dissolve in water.
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
