. Write the following characteristics of Electrochemical series


Best Answer

 

ii. Weakly electronegative metals in the upper part can displace more electronegative metals below them from their salts. For example, iron displaces copper from CuSO4 solution 

iii. Hydroxides of metals in the upper part of the series are strongly basic and their salt do not undergo   hydrolysis. On the other hand, hydroxides of metals in the lower part of the series are weakly basic and their salts undergo hydrolysis. 

iv.  Metals lying above hydrogen are easily rusted. Those situated below are not rusted. 

v.  Metals above hydrogen displace hydrogen from dilute acids. 

vi. More weakly electronegative metals like K , Na , Ca, etc. displace hydrogen from water. 

vii. Iron and other metals above it decompose steam and liberate hydrogen

viii.  Oxides of iron and other metals below it can be reduced easily.

ix. Oxides of manganese and other metals above it are reduced when heated in a current of hydrogen.

x. Oxides of mercury and other metals below it are decomposed on heating.
