Is copper hydrogen carbonate soluble in water?
Yes, but copper hydroxide will precipitate.
When carbon iv oxide is bubbled through calcium hydroxide what is the white precipitate formed?
The precipitate formed is Calcium Carbonate (CaCO3).
Describe the test for aluminium ions?
Test: Add aqueus sodium carbonate solution, then warm it. Observation: Formation of white precipitate. Deduction: The presence of aluminum ions, Al3+ Or Test: Observation: Add aqueous sodium hydroxide White precipitate occur Add aqueous sodium hydroxide (excess) & warm White precipitate solute Test with red litmus paper Changes red - blue Deduction: The presence of aluminum ions, Al3+
How to tranform cupric sulfate to cupric hydroxide?
Put drops of Sodium, Potassium, or Ammonium Hydroxide in it. The Cupric hydroxide will precipitate out in blue colour. Dont put excess hydroxide or there will be a formation of another intense blue complex compound
How do you distinguish sodium hydroxide and sodium acetate?
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz

Yes, but copper hydroxide will precipitate.
What happens when you mix calcium hydroxide and sodium hydrogen carbonate?
chalky white precipitate
When carbon iv oxide is bubbled through calcium hydroxide what is the white precipitate formed?
The precipitate formed is Calcium Carbonate (CaCO3).

How do you test presence of carbon dioxide?
Bubble the gas through limewater (calcium hydroxide), and then a white precipitate is formed, which is actually calcium carbonate.
What is the precipitate formed from ammonium carbonate and calcium nitrate?
The chemical equation for the reaction is: (NH4)2CO3 + Ca(NO3)2 → CaCO3 + 2NH4NO3 The precipitate formed is calcium carbonate and it appears as a white precipitate.
How to tranform cupric sulfate to cupric hydroxide?
Put drops of Sodium, Potassium, or Ammonium Hydroxide in it. The Cupric hydroxide will precipitate out in blue colour. Dont put excess hydroxide or there will be a formation of another intense blue complex compound
Why do we test the gas given off with limewater?
Limewater (calcium hydroxide) react with carbon dioxide and form insoluble, white precipitate of calcium carbonate.
How do you distinguish sodium hydroxide and sodium acetate?
To test presence of Sodium ions, do a flame test: color observed: golden yellow. To test presence of carbonate or hydrogen carbonate ions: Take some of the sodium hydrogen carbonate in a dry test tube. Heat the test tube and bubble the gas through limewater. Limewater turns milky. Carbonate or hydrogen carbonate ions present. To distinguish between carbonate and hydrogen carbonate: Add indicator solution. If colour of solution turns green, pH is 7-8, hydrogen carbonate ions are present. If colour of solution turns blue, pH is 12-13, carbonate ions are present. -Iberuz
What precipitate is formed from beryllium chloride and sodium hydroxide?
Beryllium hydroxide
What is a positive test for carbon dioxide?
Absorbed carbon dioxide in calcium hydroxide produce calcium carbonate, a white precipitate.
What is the word equation for the green precipitate of copper carbonate and sodium sulphate solution?
Copper(II) carbonate is insoluble in water and doesn't react with sodium sulfate. A green product, visible on ald objects made from copper or copper alloys, is a mixture of copper carbonate and copper hydroxide.
