Iron is such an important element that there is an entire period of human history called the Iron Age. There is a brown coating on the iron nail which was dipped in the copper sulphate solution, whereas the iron nail placed in petri dish shows greyish colour of iron. …, . This reaction shows that iron is more reactive than copper as it displaces copper from its solution and iron passes … Brown deposits that appears on iron nails Is due to deposition of: A) iron on iron nails done clear. So this reaction is a chemical change. Examples of physical properties include: color, shape, size, density, melting point, and boiling point. Most of the combination reactions are exothermic in nature. nH 2 O and iron(III) oxide-hydroxide (FeO(OH), Fe(OH) 3).It is typically associated with the corrosion of refined iron..
