which of the followingstatementis truefor theelectrochemical daniellcell

Answer»

electronsflowfromcopperelectrode tozincelectrode
currentflowsfrom ZINC electrodeto copper ELECTRODE
caationmove towards copperelectrode
cations movetoward zincelectrode

Solution :In Daniell cell followingreactionoccurs
`ZN+Cu^(2+) rarr Zn^(2+) +Cu`
At cathode `Cu^(2+) rarr Zn^(2+) +cu`
At anode `Zn rarr Zn^(2+) +2e^(-)`
Electrons moves from anode (Zn) to cathode(Cu) andelectricity flowsfrom Cu to Zn herecation move toward cathode copper electrode
