Most people think that Cupric sulfate or Copper(II) sulfate, is blue in colour. But actually it is not. Blue colour in Copper(II) sulfate is due to the presence of Water molecules in it. This form is called Copper(II) sulfate Pentahydrate[CuSO4.5H2O], which most people see. If it does not have any water molecules in it, the thing is in pure state and is White in colour. This form is Anhydrous Copper(II) sulfate[CuSO4]. This form is rarely seen, because it can absorb water itself from the nature and become blue in colour. So from this we know that very pure Copper(II) sulfate is not blue, But its Pentahydrate form is blue.

How many moles are in 44.78 g of cupric sulfate?
CuSO4 (cupric sulfate) has a molecular weight of 159.602g/mol Cu=63.546 S =32.06 O = 15.999 x 4 =63.996 Add the atomic weights of the elements in cupric sulfate. This is 159.602 grams/mol. Now divide the number of grams( 44.78) by the molecular weight of cupric sulfate (159.602). 44.78 g CuSO4/159.602 g/mol CuSO4= .2805 mol(moles) of cupric sulfate. The answer is 0.2805

How to tranform cupric sulfate to cupric hydroxide?
Put drops of Sodium, Potassium, or Ammonium Hydroxide in it. The Cupric hydroxide will precipitate out in blue colour. Dont put excess hydroxide or there will be a formation of another intense blue complex compound

When black copper oxide is added to dilute sulphuric acid what colour is the soloution at the end?
Blue cupric sulfate solutionAdded:Chemical formulas:- CuO, Cu(II)-oxide, cupric oxide (monocopper oxide), black- Cu2O, Cu(I)-oxide, cuprous oxide (dicopper oxide), red- sulfuric acid, H2SO4CuO + H2SO4 --> CuSO4 + H2O , cupric sulfate, blue solutionCu2O (red) also reacts with dilute sulfuric acid forming CuSO4 by:Cu2O + 2 H2SO4 --> CuSO4 + H2O + H2, cupric sulfate, blue solution
A metal whose plus 2 ions form a blue aqueous solution?
Sounds like copper (II) sulfate (ie cupric sulfate or CuSO4)
