Copper carbonate and limewater?
Copper Carbonate (CuCO3) is heated up so that a decomposition reaction occurs, with the products being Copper (II) Oxide (CuO) and Carbon Dioxide (CO2). The chemical formula is: CuCO3 --> CuO + CO2. If proper apparatus is set up, the carbon dioxide should travel down a tube into limewater (Ca(OH)2), which react to create solid calcium carbonate (CaCO3, also known as chalk) and water (H2O). The calcium carbonate is the reason why the 'limewater' turns milky. This proves that there is CO2 present. The chemical formula for this is: Ca(OH)2 + CO2 --> CaCO3 + H2O.
What happens when you mix Calcium Chloride with Copper Sulfate?
When calcium chloride is mixed with copper sulfate, a white precipitate of calcium sulfate forms due to the displacement reaction between calcium and copper ions. This reaction is a double displacement reaction in which calcium sulfate and copper chloride are formed.
What is the industrial name for gold mixed with copper?
The industrial name for a gold-copper alloy is Rose Goldor Tumbaga.If you also add silver to the alloy you get Electrum.
What happens when copper sulfate and steel wool is mix?
IF THE COPPER SULFATE DISSOLVES IN WATER, HAS A BLUE COLOR. WHEN STEEL WOOL IS MIXED WITH COPPER SULFATE,, THE STEEL WOOL DISSAPEARS, A BROWNISH SOLID FORMS, AND THE COLOR OF THE SOLUTION CHANGES FROM BLUE TO GREEN.Copper is produced.
What happens when sodium phosphate is mixed with Copper sulfate?
This will give a precipitate (s) of the insoluble copper phosphate2Na3PO4 + 3CuSO4 --> Cu3(PO4)2(s) + 3Na2SO4or (better without the soluble and not reacting ions (tribuned ions):2PO43- + 3SO42- --> Cu3(PO4)2(s)
What happens if acid is mixed with copper?
it depends what acid it is
What does copper II carbonate and limewater form?
When copper II carbonate is added to limewater, a chemical reaction occurs where the carbonate ions in the copper II carbonate react with the calcium hydroxide in the limewater to form insoluble copper II hydroxide. This results in a color change as the solution turns from clear to a blue-green color due to the formation of copper II hydroxide precipitate.
What happens to the limewater if the gas is present?
If a gas is present in limewater, such as carbon dioxide, it will react with the limewater to form a white precipitate of calcium carbonate. This reaction causes the limewater to become cloudy or milky in appearance. It is a common test for the presence of carbon dioxide gas.
What happens if vinegar and limewater were mixed together?
When vinegar and limewater are mixed together, a reaction would occur between the acetic acid in the vinegar and the calcium hydroxide in the limewater. This reaction would produce calcium acetate, water, and carbon dioxide gas. The carbon dioxide gas would be seen as bubbles forming in the mixture.
What happens to liqiud when testing for carbon dioxide?
Limewater - if you bubble Carbon Dioxide through limewater it will go cloudy!
What happens to limewater in presence of oxygen?
Nothing in particular.
What happens when sulphuric acid is mixed with copper oxide and heated?
When sulfuric acid is mixed with copper oxide and heated, a chemical reaction occurs. The copper oxide reacts with the sulfuric acid to form copper sulfate and water. The reaction is exothermic, meaning it releases heat.
What happens to limewater when carbon dioxide is bubbled through it and why?
It goes cloudy.
What happens to limewater at the end of an experiment?
At the end of an experiment, limewater will turn cloudy if carbon dioxide was present in the environment, causing it to react with the calcium hydroxide in limewater to form calcium carbonate, which is insoluble and appears as a white precipitate. If there was no carbon dioxide present, limewater will remain clear.
What happens when tin is mixed with copper sulphate?
No product is produced. Both cooper and tin are not reactive metals.
What happens to Copper sulfate and sodium hydroxide when mixed together?
When copper sulfate and sodium hydroxide are mixed together, a double displacement reaction occurs. The copper ions from copper sulfate react with hydroxide ions from sodium hydroxide to form a blue precipitate of copper hydroxide. The resulting solution will contain sodium sulfate.
What happens in the cycle of heating limewater?
cuz there is carbon dioxide in there so it is let out
