Question

rearrange the followings metal increasing order of their reactivity series lead calcium zinc tin iron magnesium sodium potassium Copper Gold Platinum silver aluminium​

Answer 1

Answer:

Answer

(a) The arrangement of metals in a vertical column in the order of decreasing reactivities is called reactivity series. The reactivity series follows the order:

K>Na>Ca>Mg>Al>Zn>Fe>Pb>H>Cu>Hg>Ag>Au

(b) Lead is more reactive than hydrogen and copper is less reactive than hydrogen

(c) Zinc displaces copper from copper sulphate solution and mercury does not displace copper from copper sulphate solution

(d) Copper displaces silver from silver nitrate solution and gold does not.
