If you do electrolysis with copper electrodes in a solution of sodium carbonate what is the blue stuff left in the solution?
Jordehwa
i don't know what u are doing wrong as u should not be able to oxidize copper with such a solution but it can only be copper hydroxide (Cu(OH)2)

Why does the blue colour remains blue during electrolysis of copper sulphate solution using copper electrodes?
During the electrolysis of Copper sulphate ,at the cathode ,copper and hydrogen both being positively charged migrate towards the cathode.While at the anode
What is the reaction equation of electrolysis of water with copper electrodes?
The electrolysis of water produces oxygen and hydrogen gas. 2H2O --> 2H2 + O2
How is copper released from a copper sulphate solution?
silicate, carbonate or sulphate
Why does the most dilute solution deposit more copper in electrolysis?
An electrolysis process is based upon movement and flow of ions. More is the solution dilute, more is the movement of ions and more is the conductance of solution. Thus, when the solution is dilute more copper ions flow to the electrode and get deposited there
Why does the color of copper sulfate solution changes during electrolysis?
The color fades as there is a discharge of copper two ions to form copper atoms

What is the name of the process that uses electrodes to purify copper?
Electrolysis
What are inert and active electrodes?
Inert electrodes simply serve as electrical conductors and are unchanged by the cell processes. Active electrodes change during the cell reactions. An example of inert electrodes is platinum in the electrolysis of water. The platinum remains unchanged and the water is split into hydrogen and oxygen. An example of active electrodes is in the electrolysis of copper sulfate solution with copper electrodes. The anode copper is converted into copper ions in the solution, and metallic copper builds up on the cathode. The term active electrode is also used in eeg measurement, here as the opposite to passive electrode. Electrodes are the pads attached to the skin to get readings, and active ones don't need a conductive paste to get a good signal.
What will affect the electrolysis of molten copper chloride?
temperature and potential difference of electrodes.

What is the acid that reacts with copper 2 carbonate to give a blue solution?
When dilute sulfuric acid reacts with copper(II) carbonate, blue copper(II) sulfate solution is produced.

What are the metal strips called that are placed in the copper compound solution during electrolysis?
electrode
Why does the color of copper sulfate solution changes during electrolysis?
The color fades as there is a discharge of copper two ions to form copper atoms
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.
Why did your light bulb stay lit after you removed it from the copper sulfate solution?
My lightbulb stayed lit after I removed it all from the copper sulfate solution because electrodes were still working.
