1-if we put ame tal in its salt soln it may ...or ....
dissolved &deposited
2-if cu+2.......incu electrodeit will give cu
write eq
cu+2+2e_______cu
3-if we put Ni met al in Niso4.it will be...write reason
dissolve
as Ni is avery reactive met al
4- M] in its....or ....form equal nearly.]
....انا مش فاهمة السؤال ده
5-Due to presence of ..........the currrent passes and this current measured by..........why?
potential differance &galvanometer بصراحة مش عارفة ليه
6-in case of using cu,zn celll and Nacl as asalt in salt bridge
what,s the problem which will face you?
problem is :accumlation of ion Cl-on the electrode leads to polarization
as ionic mobility of Nacl
Na=50.1
cl=76.3
7-the cell consumes electricity is known as............cell
galvanic cell
