Question

state what happens when hyrated sulphate is heated

Answer 1

WHEN HYDRATED SULPHATE IS HEATED THEN IT LOSES THE WATER MOLECULES IN IT

Answer 2

Water is driven out from the hydrated copper sulphate when it is heated.The color of the crystals slowly turns from blue to white  .This is becoz  heat causes the crystals to lose their water of crystallization which gives them the blue color.This reaction when heated with water is reversible ,i.e,the white crystals can change colour back to blue when a few drops of water r added. A mist of water droplets formed on the upper cooler portion of any apparatus .it changes from crystalline to amorphous.
