What colour is copper oxide and why?
Copper has two oxides. Copper (I) oxide is red, while Copper (II) oxide is black.
What is the color of precipitate of copper II oxide from copper II hydroxide?
Well if u want the colour of precipitate of Copper II Oxide, that would be black, if its Copper I Oxide then its Red
When copper is heated in air what colour is the copper oxide formed?
GreenAdded:There are two copper oxides, differing in color:if it is black powder, then it is copper(II) oxide CuO (cupric, more common, as in the mineral 'tenoriet')if it is red powder, then it is copper(I) oxide Cu2O (cuprous oxide, as in mineral the 'cupriet' and it occurs in 'Benedict's test' on reducing sugars)
What color effervescense when sulfuric acid and copper oxide are mixed?
What is the colour of the solution formed when copper oxide is dissolved in dilute sulphuric acid? it turns blue!!!!!!!!!!!!!!!!!!!
When you dissolve copper oxide in water and add universal indicator what colour do you see?
a green one

Is copper oxide green or black?
The colour of copper(II) oxide is black, while that of copper(I) oxide is red. The green colour you see on the Statue of Liberty is because carbon dioxide in the air reacted with the copper to produce copper(II) carbonate, which is greenish-blue.
What is the color of precipitate of copper II oxide from copper II hydroxide?
Well if u want the colour of precipitate of Copper II Oxide, that would be black, if its Copper I Oxide then its Red
What is the colour change when copper oxide is added to hydrogen?
Copper oxide is black and when reacted with Hydrogen is REDUCED to elemental copper which is "copper" colored or red-brown
What is the compound Cu20?
Cu2O, where the 2 should be a subscript, is copper(I) oxide or cuprous oxide to give it its old name. It is found naturally as the ore cuprite. It is a red-brown powder, whereas the copper(II) oxide we see when copper is heated is black.

Can copper be broken down by chemical means?
Yes, if copper is exposed to wood, it decomposes rather quickly.
What would be the colour of the solution when copper oxide and dilute hydrochloric acids are mixed?
Blue
What distinguishes a compound like copper sulfate from an ordinary mixture of copper powder sulfur?
There are two copper oxides. Copper I oxide (Cu2O) and copper II oxide (CuO) both contain copper and oxygen. Copper II oxide is a reddish solid and Copper II oxide is a black solid. Both are insoluble in water. Copper sulfate (CuSO4) contains copper, sulfur, and oxygen. It is most often found in its hydrated form as a blue solid, but allso occurs in its anhydrous form as a white solid. It is soluble in water.
What is the name for the compound Cu2O?
Copper (I) Oxide or Cuprous Oxide
When you dissolve copper oxide in water and add universal indicator what colour do you see?
a green one
