For the best results reaction should take place in the slightly acidic solution (pH around 4-5), correct pH is obtained by addition of acetic acid.

Can copper sulphate be prepared from copper metal and dilute sulphuric acid?
No, it cannot be prepared by this method under normal conditions. For preparing copper sulphate, copper should be added to the sulphate salt of a metal which is less reactive than copper like Mercury, silver and gold
What method is used to separate copper from copper sulphate solution?
By heating copper sulfate is decomposed in copper(II) oxide and sulfur trioxide; by reduction of the copper oxide with hydrogen copper is obtained.
Method for manufacturing copper sulphate?
There are various method for manufacturing copper sulphate commercially. it can be manufactured by the action of sulphuric acid on copper in the presence of air/O2. reacting copper with dilute sulphuric acid in the presence of strong oxidising agents like HNO3. By converting copper into copper oxide and dissolution of oxide into dilute sulphuric acid. once we get liquid copper sulphate solution from reaction then the normal operations are filtration , concentration, crystallisation, separation & drying of crystals
How do you purify copper sulphate?
By the method of electrolysisCopper is a good conductor of electricity, and is used extensively to make electrical wiring and components. The extraction of copper from copper ore is done by reduction with carbon, but the copper produced is not pure enough for use as a conductor, so it is purefied using electrolysis.

What is the industrial preparation method of copper sulphate?
The scrape orwasted copper pieces are boiled in sulphuric acid in open air then mixture is worked up with water.
Difference between iodometry and iodimetry?
When an analyte that is a reducing agent is titrated directly with a standard iodine solution, the method is called "iodimetry". When an analyte that is an oxidizing agent is added to excess iodide to produce iodine, and the iodine produced is determined by titration with sodium thiosulfate, the method is called "iodometry".

How do you separate powdered copper sulphate and powdered chalk?
Well, you need to get a beaker and add water.Then add the powdered chalk and add copper sulphate to the beaker.Then get a conical flask with a funnel and get some filter paper and fold it into a funnel and place it the funnel in the conical flask then mix your solution with a stiring rod and pour down funnel .What you should end up with is copper sulphate with the water in the conical flask and the chalk mix in the filter paper.
What is idometry?
Iodometry, also known as iodometric titration, is a method of volumetric chemical analysis, a redox titration where the appearance or disappearance of elementary iodine indicates the end point.
