CuSO4(aq) + 2 NaOH(aq) --> Cu(OH)2(s) + Na2SO4(aq)
you get a blue lumpy liquid. copper sulphate + sodium hydroxide -> copper hydroxide + sodium sulphate.
Copper sulfate is a reactant in the equation as stated, because it is present before the reaction has occurred and no longer present afterward.
Calcium sulphate + Sodium hydroxide > Sodium sulphate + Calcium hydroxide
Nothing
how the end point is determined

a big lump of mess i dont think so copper sulphate +sodium hydroxide = Na2So4 +Cu(OH)2 WHICH IS SODIUM SULPHATE AND COPPER HYDROXIDE
Biuret reagent is made up of sodium hydroxide and copper sulphate.
Nothing
it starts changing to white because the colour of the copper sulphate solution becomes whote during the process of evaporation
Fehling's solution A= concentrated aqueous solution of Copper (II) sulphate, Fehling's solution B= solution of Sodium-potassium tarterate + sodium hydroxide.
No amount of sodium sulphate can be formed from sodium hydroxide alone, because sodium sulfate contains sulfur and sodium hydroxide does not. By neutralization with sulphuric acid, one formula unit of sodium sulphate can be formed from two moles of sodium hydroxide, according to the equation 2 NaOH + H2SO4 -> Na2SO4 + 2 H2O.
how the end point is determined
Nowhere. I assume you are talking about mixing solutions. The sodium ions and sulpahate ions remain in solution.
Copper(II) carbonate is insoluble in water and doesn't react with sodium sulfate. A green product, visible on ald objects made from copper or copper alloys, is a mixture of copper carbonate and copper hydroxide.
