Скачать или смотреть Class 10: Chemistry: CORROSION OF METALS:& RUSTING OF IRON: NCERT & CBSE

In this video lecture - I have delivered a brief explanation on Corrosion of metals. Those reactive metals lying at the top of the metals reactivity series have the tendency to undergo corrosion. Corrosion are nothing but when metal left expose to air and moisture for sufficient length of time - we observes a kind of oxide layers settles on the surface of the metals. This oxide layers slowly begin eating or damaging the metallic texture and properties in a very large degree. This ultimately results in decreasing the overall strength, longevity and durability of the metals. For example rusting of Iron. Another metal although very less reactive in nature known as silver when exposed to air and moisture starts reacting with hydrogen sulphide forming Silver sulphide (black coating on silver metal) and hydrogen gas goes to air.
