1.	When ferrus sluphate is heated what is the change of colour
Answer» Green flame Green to white The colour of ferrous sulphate is green. It changes to brown after heating.On heating:\xa0FeSO4\u200b.7H2\u200bO→FeSO4\u200b(s)+7H2\u200bO(g)The product formed is ferric oxide (Fe2\u200bO3\u200b). This is a decomposition reaction.On strong heating:\xa02FeSO4\u200b(s)→Fe2\u200bO3\u200b(s)+SO2\u200b(g)+SO3\u200b(g It gives ferric oxide , sulphur dioxide and sulphur trioxide
