(i) metal ‘A’ which is one of the last, second or third positions in the reactivity. (ii) metal ‘B’ which gives a vigorous reaction even with water and air. (iii) metal ‘C’ which is kept in the middle df activity series. Answer: (i) Chemical reduction using carbon or carbon...
On the basis of reactivity of different metals with oxygen, water and acids as well as displacement reactions, the metals have been arranged in the decreasing order of their reactivities. This arrangement is known as activity series or reactivity series of metals. The basis of reactivity ...
