How much copper is deposited if a current of 0.2 amps is passed for 2 hours through a copper II sulphate solution?

that would depend on the area of the surface being plated

What is observed when electric current is passed through copper sulphate?
its colour changes 2 blue
How will you obtain pure copper sulphate crystal?
boil off the solvent (usually water) until you are left with copper sulfate crystals. For getting back the copper sulphate crystals from copper sulphate solution, we have to first make super saturated solution by boiling, then allow to cool down & dried these crystals with filter paper.
How do you separate chalk and copper sulfate?
Chalk (Calcium carbonate) is insoluble. Copper sulphate is soluble. To separate, first place the mixture in wter. The copper sulphate will dissolve, the chalk will not dissolve. When the copper sulphate is fully dissolved, filter the solution. The copper sulphate component will pass through the filter paper, but the chalk will remain in the filter paper. Dry the filter paper to obtain the dry chalk. Evaporate the solution to dryness, to obtain the blue dry copper sulphate crystals.
Would an electric current be completed in NaCl solution?
yes, the charges of the dissolved ions in solution allow for electrons to be transfered through water. Completely pure water actually is a decent insulator of electric current
Separate chalk from a mixture of chalk and copper sulfate solution?
Filter. The copper sulphate will pass through the filter paper. The undissolved chalk will remain in the filter paper.
What happens when current passes through copper sulphate solution?
I don't know. Ask your chemistry teacher. Sincerely, a girl who doesn't know.

Why does current pass through salt solution but not through sugar solution?
In order to pass current through a solution you need to have ions in it. Table salt (NaCl) dissolves into Na+ and Cl- ions. Meanwhile sugar does not dissociate into ions in a water solution.

A bulb glows dimly when current is passed through a vinegar solutionwhy?
The bulb glows dimly when current is passed through a vinegar solution because the small number of ions in the vinegar solution move through the filament of the bulb.
What happens when electric current is pass through a colloidal solution?
it will get hot

What are the factors on which the current through an electrolyte depends?
The factors on which the current through an electrolyte depend are: (i) Nature of electrolyte (ii) Concentration of the solution (iii) Temperature
How is the electric current carry through the solution of the ionic compounds?
by moving the ions
Do magnetic effect of electric current causes a change in colour in a solution through which electric current is passed?
i don't believe it does
How does acid strength affect electrical conductivity?
The strength of an acid depends of the number of hydrogen ions in solution- the stronger the acid the more hydrogen ions there are in solution. Hydrogen ions in solution carry current, therefore the more hydrogen ions in the solution the more current there will be carried through solution.
