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 sodium chloride solution is obtained.
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.
When gaseous H2S is passed through aqueous CuSO4, a black precipitate of Copper Sulphide (CuS) is formed with sulphuric acid solution.
You create magnesium sulfate and zinc through single discplacement/replacement.Zinc sulfate(aq) + Magnesium (s)->Magnesium sulfate + Zinc (s)ZnSO4(aq)+ Mg (s) -> MgSO4 + Zn(s)Hope it helps ;)

it will get hot
that would depend on the area of the surface being plated
Either the bulb will start glowing or the magnetic needle will show deflection
its colour changes 2 blue

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.
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.
The factors on which the current through an electrolyte depend are: (i) Nature of electrolyte (ii) Concentration of the solution (iii) Temperature
analysis purpase
by moving the ions
When a strong beam of light is passed through a colloidal solution, then scattering of light is absorbed.
