Decribe Leclanche cell.

The most common dry cell is the Leclanche cell. It consists of a carbon (graphite) rod as cathode which is surrounded by by powdereed "_______" and carbon black.

In the dry cell or Leclanche cell, a carbon rod serves as the cathode, which is immersed in the electrolyte in the center of the cell. At cathode, manganese is reduced from the "_______" oxidation state to the "_______" state.

Following are some of the facts about a dry cell I : It is alos called Leclanche cell II : It is also called Daniel cell III : Electrolyte is a moist paste of NH_(4)Cl and ZnCl_(2) in starch IV : Cathodic reaction is 2MnO_(2)(s)+2NH_(4)^(+)(aq)+2e^(-) rarrMn_(2)O_(3)(s)+2NH_(3)(g)+H_(2)O(l) Select correct facts :

The positive electrode of a Leclanche cell is made of

Which of the following is a false statement about Leclanche cell ?

The porous pot in Leclanche cell contains "_____" with a carbon rod dipped in it.

An alkaline dry cell is similar to the Leclanche cell, but it has "_______" as the electrolyte in place of ammonium chloride.
