Which is/are concentration cells ?

Answer»

<P>pt , `H_2 // HCl // // HCl // H_2` , pt
Pt : `H_2 // UNDERSET((P^(H)=4))(HCl)// underset((P^(H)=2))(HCl)// H_2, Pt `
`Ag // underset((1M))(AgCl)// underset((1M))(AgBr)//Ag `
`Ag // underset((s))(AgCl), KCl // underset((1M))(AgNO_3)// Ag `

Solution :If 2 plates of same metal are dipped seperately into two solutions of same electrolyte and are connected with a salt bridge LIKE Gavanic cell called concentration cell.
Electrode concentration shell ` (Pt, H_2 (P_1))/("anode")|H^(+)|(H_2(P_2) Pt)/("cathode") , M(HgC_1)|M^(N+)|Zn(HgC_2)`
Electrolyte concentration cel `M|M^(n+) (C_1) ||M^(n+) (C_2) | M , (Zn|Zn^(+2)(C_1))/("anode")||(Zn^(+2)(C_2)|Zn)/("cathode")`
