What will happen during the electrolysis of aqueous solution of cuso4 by using carbon electrodes?

Copper will dissolve at anode.

What happens to copper sulfate during electrolysis?

So it can be concluded that, during electrolysis of copper sulfate with copper electrodes, copper is deposited on cathode and same amount of copper is removed from anode.

What will be observed when the electrolysis of copper II sulfate solution is performed using copper electrodes?

When copper electrodes are used in the electrolysis of copper sulfate solution, the mass loss of copper from the positive anode electrode should equal the mass of copper gained and deposited on the negative cathode electrode. You can show this by weighing both electrodes at the start of the experiment.

How do you concentrate sulphuric acid?

You can concentrate the sulfuric acid by either saturating the water with SO3 to make Oleum or by boiling off water to reach the sulfuric acid azetrope of 98\%.

How do you make pure sulphuric acid?

In the first step, sulfur is burned to produce sulfur dioxide. This is then oxidised to sulfur trioxide using oxygen in the presence of a vanadium(V) oxide catalyst. Finally the sulfur trioxide is treated with water (usually as 97-98\% H2SO4 containing 2-3\% water) to produce 98-99\% sulfuric acid.

When CuSO4 is Electrolysed by platinum electrode then?

The blue colour of aqueous copper sulphate fades when it is electrolysed using platinum electrodes.

When CuSO4 solution is Electrolysed substance formed at anode is?

copper metal is formed at the negative electrode. oxygen gas is formed at the positive electrode.

How does electrolysis make copper sulphate?

Make Copper Sulfate

1. Fill a jar or beaker with 5 ml concentrated sulfuric acid and 30 ml of water.
2. Set two copper wires into the solution so that they are not touching each other.
3. Connect the wires to a 6-volt battery.
4. The solution will turn blue as copper sulfate is produced.

What is produced at the anode when copper sulphate is electrolysed?

oxygen gas is formed at the positive electrode.

What products will be made during the electrolysis of Sulphuric acid h2so4?

Electrolysis of dilute sulfuric acid

• H + ions are attracted to the cathode, gain electrons and form hydrogen gas.
• OH – ions are attracted to the anode, lose electrons and form oxygen gas and water.

Why is Sulphuric acid highly viscous?

Sulphuric acid is highly viscous in nature because its molecules are associated with hydrogen bonding. It is a highly corrosive chemical. It is also used as a sulphonating agent in organic reactions.

What happens if you add sulfuric acid to copper sulfate solution?

3 Answers. It will also increase the conductivity of your solutions tremendously, because hydrogen ions are extremely mobile. The solubility of copper sulfate decreases with increasing sulfuric acid concentration, so don’t add too much acid.

How do you make copper sulfate at home?

1 Fill a jar or beaker with 5 ml concentrated sulfuric acid and 30 ml of water. If your sulfuric acid solution is already diluted, add less water. 2 Set two copper wires into the solution so that they are not touching each other. 3 Connect the wires to a 6-volt battery. 4 The solution will turn blue as copper sulfate is produced.

How do you dilute sulfuric acid to make copper wire?

Fill a jar or beaker with 5 ml concentrated sulfuric acid and 30 ml of water. If your sulfuric acid solution is already diluted, add less water. Set two copper wires into the solution so that they are not touching each other.

Why does CO2 not react with dilute sulphuric acid?

Copper does not react with dilute sulphuric acid as its reduction potential is higher than that of hydrogen. Copper does not displace hydrogen from non-oxidising acids like HCl or dilute H2SO4. But, concentrated sulphuric acid is an oxidising agent.
