Copper(II) nitrate crystallises as a hydrate Cu(NO3)2 ' x H20
In order to determine the number of mole of water in a mole of the hydrate, 2.416 g of the blue, hydrated
crystals was carefully heated to remove the water, 1.876 g of the anhydrous Cu(NO3)2 was left.
(a) Write a balanced equation for the heating of Cu(NO3)2 X H2O.
(b) Use these data to determine the value of x (the number of mole of water per mole of Cu(NO3)2 x H2O.
(x = 3)
%3D
(c) Unfortunately, one student heated the compound too strongly and some of the copper(II) nitrate
decomposed to produce NO2(E) and O2(e)
Balance the equation for the decomposition:
Cu(NO3)2(5)
CuO(s)
NO2(8)
O2(e)
