What is the function of acidified copper sulphate solution?

The lower pH of Acidified Copper Sulfate insures that more copper goes into solution, reducing your costs and providing a more efficient operation. The product is especially efficient in areas with hard water.

What will happen during the electrolysis of aqueous solution of copper sulphate in the presence of copper electrodes?

Copper will dissolve at anode.

What is hydrolysis of copper sulphate?

Hydrolysis is the interaction of anion or cation of the salt with water to produce an acidic or basic solution. For example: An aqueous solution of copper sulphate is acidic whereas the aqueous solution of the sodium acetate is basic in character.

How does sulphuric acid prevent hydrolysis of copper sulphate?

SO4 2- doesn’t hydrolyze appreciably as H2 SO4 is a fairly stronger acid than water. So on adding H+, due to common ion effect, the equilibrium of the Cu2+ hydrolysis is shifted to the left. In other words, hydrolysis decreases.

What products are obtained when hydrolysis of copper sulphate is carried out?

The products of electrolysing copper sulfate solution with inert electrodes (carbon/graphite or platinum) are copper metal and oxygen gas.

What happens in the electrolysis of copper sulphate?

– Electrolysis is the process in which an electrolyte, in this case copper sulphate solution, undergoes redox reactions at the electrodes due to the action of electric current. -At Cathode, reduction takes place. Cupric ions present in the electrolyte gain two electrons and get converted to copper metal.

What happen if a solution of copper sulfate cuso4 is electrolyzed using copper Cu electrodes?

When Copper(II) sulfate is electrolysed with a copper anode electrode (the cathode can be carbon or copper), the copper deposit on the cathode (–) equals the copper dissolves at the anode (+). Therefore the blue colour of the Cu2+ ions stays constant because Cu deposited = Cu dissolved.

Which statement about the electrolysis of an aqueous solution of copper II sulfate with platinum electrodes is correct?

Statement : At the end of electrolysis using platinum electrodes, an aqueous solution of copper sulphate turn colourless. Explanation : Copper in copper sulphate is converted to copper hydroxide during the electrolysis. S is wrong but E is correct.

What is the action of litmus on aqueous solution of copper sulphate?

Detailed Solution Aqueous solution of copper sulphate turns blue litmus red as it is acidic in nature.

What is the purpose of adding dilute sulphuric acid in copper sulphate solution during crystallization process?

After looking you can be copper sulphate crystals being separated out. In water, when copper sulphate is dissolved, it tends to form a complex with water by hydrolysis. Hence to prevent that a small amount of sulphuric acid is added.

Why do we add acid in the electrolysis of copper sulphate?

Copper sulphate will not react easily. So for reaction there is need of break down of electrolyte and so some acid is added so that it can break into cation and anion and can help the reaction . , Knows some of it, sort of..

Is copper sulphate an acid or base?

Copper sulphate is a salt of a strong acid, H2SO4, and a weak base, Cu (OH)2. The release of H+ ions by hydrolysis makes the solution distinctly acidic. Originally Answered: Why copper sulphate is acidified?

What is hydhydrated copper sulphate?

Hydrated copper sulphate is CuSO4.5H2O, blue crystalline solid in which 4 water molecules are directly attached with Cu++ through coordinate bonds and 5th water through H-bonding. However note that coordination number of Cu++ in this solid is 6 ( 4 water ligands, two sulphate ligands). Hope it helps!

How does acidification of water help in the dissociation of ions?

I understand (more or less) that acidification of water helps in the dissociation of water into ions. Acids easily dissociate into ions in aqueous solution. So, accordingly, the hydrogen from the acid goes to the cathode and the hydrogen from the water makes a compound with the negative radical from the acid.
