Metal Reactivity The Reactivity Series. Based on how they react with other substances, a reactivity series can be produced in which the metals are placed in order of their reactivity Metal atoms form positive ions by loss of electrons when they react with other substances The tendency of a metal to lose electrons is a measure of how reactive the metal is

Sustainable Water Supply. The demand for water has increased over the last 100 years due to an increasing population and a greater need for it in agriculture and industry . Climate change could also result in water shortages all over the world, including the UK which would cause the cost of water to increase. As a result we need a sustainable water supply

The reactivity between two metals can be compared using displacement reactions in salt solutions of one of the metals. This is easily seen as the more reactive metal slowly disappears from the solution, displacing the less reactive metal. For example, magnesium is a reactive metal and can displace copper from a copper sulfate solution:
