Copper(II) hydroxide can be produced by adding a small amount of sodium hydroxide to a dilute solution of copper(II) sulfate (CuSO4 · 5H2O). The precipitate produced in this manner, however, often contains water molecules and an appreciable amount of sodium hydroxide impurity. A purer product can be attained if ammonium chloride is added to the solution beforehand.
Alternatively, copper hydroxide is readily made by electrolysis of water (containing a little electrolyte such as sodium bicarbonate). A copper anode is used, often made from scrap copper.

What happens when copper chloride is mixed with sodium hydroxide?
Copper chloride + Sodium hydroxide --> Copper hydroxide + sodium chloride
What happen if you add the copper sulphate to sodium hydroxide?
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
What is the product of sodium hydroxide and copper sulfate?
The products are Sodium Nitrate and Copper Hydroxide.
What is the physical state of copper hydroxide at room temp?
At room temperature, copper hydroxide is solid.
Is copper hydroxide an alkali?
Yes, anything with 'hydroxide' on the end of it is an alkali. Copper(I)- and Copper(II)-hydroxide are both very insoluble hydrates of the corresponding oxides of copper. (Cu2O.H2O = 2CuOH and CuO.H2O = Cu(OH)2 )
What happens when copper chloride is mixed with sodium hydroxide?
Copper chloride + Sodium hydroxide --> Copper hydroxide + sodium chloride
Why does copper II nitrate and sodium hydroxide make a precipitate?
when they react, it forms copper hydroxide which is insoluble, and hence a precipitate in the resultant solution of sodium nitrate
What is the formula for copper you hydroxide?
Copper hydroxide is Cu(OH)2.
Is copper soluble in sodium hydroxide?
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.
What happen if you add the copper sulphate to sodium hydroxide?
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
What is the product of sodium hydroxide and copper sulfate?
The products are Sodium Nitrate and Copper Hydroxide.
When copper ii hydroxide and sodium nitrate is heated?
you make a black precipitate.
What is the physical state of copper hydroxide at room temp?
At room temperature, copper hydroxide is solid.
What is the balanced reaction between Sodium Hydroxide and Copper Bromide?
copper bromide + sodium Hydroxide = Copper Hydroxide + Sodium Bromide CuBr2 + 2NaOH = Cu (OH)2 + 2NaBr
Is copper hydroxide an alkali?
Yes, anything with 'hydroxide' on the end of it is an alkali. Copper(I)- and Copper(II)-hydroxide are both very insoluble hydrates of the corresponding oxides of copper. (Cu2O.H2O = 2CuOH and CuO.H2O = Cu(OH)2 )
Copper reacts with sodium hydroxide?
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.
What happens when you add sodium hydroxide to copper bromide?
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.
