... If the hydrated copper sulphate is heated, it turns white as the water is given off. This requires energy so it is endothermic When water is added to anhydrous copper sulphate, it turns blue and heat is given out as the reaction is exothermic. This reaction is sometimes used as a test for water. In ...

CHAPTER 8 PERIODIC RELATIONSHIPS AMONG THE ELEMENTS
... To form the +2 ion of calcium, it is only necessary to remove two valence electrons. For potassium, however, the second electron must come from the atom's noble gas core which accounts for the much higher second ionization energy. Would you expect a similar effect if you tried to form the +3 ion of ...
