What is the color of copper carbonate when heated?
When copper carbonate is heated, it changes from its green color to black copper oxide.
Which salt changes from green to black on heating?
Copper(II) sulfate changes from green to black when heated due to the decomposition of copper(II) ions to copper(I) ions, which are black in color.
The effect of heat on copper carbonate?
When heat is applied to copper carbonate, it decomposes into copper oxide, carbon dioxide, and oxygen. The copper oxide that is formed is a black solid and is different in color from the original copper carbonate. This decomposition reaction is endothermic, meaning it absorbs heat to occur.
How does black copper oxide form?
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen
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 is the color of copper carbonate when heated?
When copper carbonate is heated, it changes from its green color to black copper oxide.
What color is copper carbonate when heated?
Copper Carbonate when heated decomposes to give copper oxide and carbon dioxide.
What is a blue solid that produces a black solid when heated?
Either sodium carbonate or copper carbonate
What colour is copper II carbonate when it is heated?
CuCO3 is bluish-greenish-white. If it is heated to a high enough temperature, it will decompose into Carbon Dioxide and Copper II Oxide, which is black.
Which salt changes from green to black on heating?
Copper(II) sulfate changes from green to black when heated due to the decomposition of copper(II) ions to copper(I) ions, which are black in color.
Why does green copper carbonate go black?
Because it undergoes thermal decomposition. If you give heat to Copper (II) carbonate, it will decompose to form Copper (II) oxide. Instead of saying green copper carbonate, I guess it is safer and better to say copper (II) carbonate.
Why does CuCO3 turns black when heated?
Copper carbonate (CuCO3) turns black when heated because it decomposes to form copper oxide (CuO), carbon dioxide (CO2), and water (H2O). This color change is a result of the chemical reaction taking place during the decomposition process, which leads to the formation of copper oxide, a black colored compound.
What solid residue will turn from green to black if heated?
Copper(II) nitrate will turn from green to black when heated due to the decomposition of the compound. The green color is due to the presence of copper ions, which decompose into copper oxide when heated, resulting in the color change to black.

Why is the black stuff on heated copper not soot?
The black substance that forms on heated copper is not soot because copper does not undergo combustion in the same way as carbon-based materials. The black substance is most likely copper oxide, formed when the copper reacts with oxygen in the air.
