घडियो में बटन सेल निम्न प्रकार कार्य करती है `Zn_((s))+Ag_(2)O_((s))+H_(2)O(l)hArr2Ag_((s))+Zn_((aq.))^(2+)+2OH_((aq.))^(-)` यदि अर्ध-सेल विभव है `Zn_(" "(aq.))^(2+)+2e^(-)toZn_((s))," "E^(@)=-0.76V` `Ag_(2)O_((s))+H_(2)O(l)+2e^(-)to2Ag_((s))+2OH_(" "(aq.))^(-),E^(@)=0.34V` सेल विभव होगाA. 1.34 VB. 1.10 VC. 0. 42 VD. 0.84 V |

Answer» `Zn_((aq.))^(2+)+2etoZn_((s))," "E^(@)=-0.76V` `Ag_(2)O_((s))+H_(2)O(l)+2eto2Ag_((s))+2OH_((aq.))^(-)E^(@)=0.34V` `E_("Cell")^(@)=E_(RP("कैथोड"))^(@)-E_(RP(" ऐनोड"))^(@)` `=0.34-(-0.76)=1.10V` `E_("Cell")=E_("Cell")^(@)=1.10V` |
