Chemical reaction:
In a zinc¡¡ìCmanganese dioxide dry battery, the zinc can is the negative terminal through which the electric current flows into the device. The zinc is oxidised according to the following half-equation.
Zn(s) ¡¡§² Zn2+(aq) + 2 e− [E¡ã = -0.7626 volts]
The positive terminal is a mixture of chemicals ¡¡ìC usually a mixture of manganese dioxide powder, carbon and an electrolyte to increase the electrical conductivity. A carbon electrode rod also is placed inside the middle of the battery, connecting the two metal-capped ends of opposite charge and serving as the positive terminal.The reaction is as follows:
2MnO2(s) + 2 e− + 2NH4Cl(aq) ¡¡§² Mn2O3(s) + 2NH3(aq) + H2O(aq) + 2 Cl− [e¡ã ¡Ö +.5 v]
and the Cl− combines with the Zn2+.
There are other possible side-reactions, but the overall reaction in a zinc¡¡ìCmanganese dioxide battery can be represented as:
Zn(s) + 2MnO2(s) + 2NH4Cl(aq) ¡¡§² Mn2O3(s) + Zn(NH3)2Cl2 (aq) + H2O(l)
We promise to provide you with high quality battery as well as high efficiency services.
