What is the colour of Crystals of copper sulphate ?

What is the colour of FeSO_4. 7H_2O crystals? How does this colour change upon heating? Give balanced chemical equation for the changes.

What Is the colour of CoCI_3.5NH_3.H_2O ?

FeO crystallizes in NaCl -type of crystal lattice. The crystals of FeO are deficient in iron and are always non-stoichiometric. Some cationic sites are vacant and some contain Fe^(3+) ions but the combination is such that the structure is elctrically neutral. The formula approximates to Fe_(0.95)O . What is the ratio of Fe^(2+) to Fe^(3+) ions in the solid?
