In dry cell whatacts as a negative electrode ?

Answer»

Zinc
graphite
ammoniumchloride
manganese dioxide

Solution :In a dry cell zinc acts as a negatvie electode in this cell the OUTER zinc ocntainer is the negatively charged TERMINAL
At anode (negative terminal )
`Zn (s) RARR Zn^(2+) (Aq) +2e^(-)`
at CATHODE (positiveterminal )
`2MnO_(2) (s) + 2e^(-)+2 NH_(3) (aq)+H_(2)O(I)+2CI^(-)`
