2 qn regarding rxn of copper sulphate

[Wen]

1.What will be produced when Cu(II)SO4 is mixed with sodium carbonate

2.What will be produced when Cu(II)SO4 is reacted with sodium carbonate and sodium hygrogencarbonate? What causes the difference between 1 &2?

Is the product for Qn2 CuCO3.Cu(OH)2aq?

Number one is a double replacement reaction, there should be an example of one in your textbook. In regards to number 2 I am not posative but i can check.

1. When Cu(II)SO4 is mixed with sodium carbonate, the products formed will be CuCO3 (copper carbonate) and Na2SO4 (sodium sulfate). This is because the copper ions in Cu(II)SO4 will react with the carbonate ions in sodium carbonate to form a precipitate of copper carbonate, while the remaining sodium and sulfate ions will remain in solution.

2. When Cu(II)SO4 is reacted with both sodium carbonate and sodium hydrogen carbonate, the products formed will be CuCO3.Cu(OH)2 (basic copper carbonate) and Na2SO4 (sodium sulfate). The difference between 1 and 2 is that in the second reaction, both carbonate and hydrogen carbonate ions are present, which leads to the formation of a basic copper carbonate instead of just copper carbonate. This is because the hydrogen carbonate ions can react with the copper ions to form a basic salt, which contains both carbonate and hydroxide ions.

The product for Qn2 is not CuCO3.Cu(OH)2aq. The "aq" indicates that the product is in aqueous form, but the basic copper carbonate formed in this reaction is not soluble in water. It will precipitate out of solution and can be seen as a solid.
