What is galvanic cell ? discuss the construction and working of daniel cell ?

Answer»

The Daniell cell consists of a zinc rod dipping in a solution of zinc sulphate, connected by a wire to a copper rod dipping in a copper sulphate (II) solution. Spontaneous oxidation and reduction reactions generate electric current, with electrons passing from the zinc rod to the wire and from it to the copper rod, originating a current along the wire.

Construction:-

In the construction of Daniel cell many chemical and non-chemical materials are used. The materials are given below:  

(i) a strip of copper 

(ii) a strip of zinc 

(iii) a large beaker, bowl or other suitable container 

(iv) a porous vase (as discussed in the Introduction) 

(v) a plastic tube 

(vi) cotton 

(vii) Copper Sulfate (CuSO4

(viii) Zinc Sulfate (ZnSO4

(ix) Potassium Nitrate (KNO3

(x) Sodium Chloride (NaCl) if Potassium Nitrate is unavailable 

(xi) distilled water 

(xii) a voltmeter two cables with alligator clips
