1.	Which of the following is concentration cellA. `Cu_((s))//Cu_((aq.1M))^(2+)\|\|\|\|Cu_((aq.1M))^(2+)//Cu_((s))`B. `Cu_((s))//Cu_((aq.0.5M))^(2+)////Cu_((aq.0.5M))^(2+)//Cu_((s))`C. `Zn_((s))//Zn_((aq.0.5M))^(2+)//Cu_((aq.1M))^(2+)//Cu_((s))`D. `.^(Theta)Pt//H_(2_("g 1 bar"))//HCl_(aq" "0.002M)////HCl_((aq.0.005M))//H_(2(g.1"bar"))//Pt^(o+)`
Answer» Correct Answer - D `.^(Theta)Pt//H_(2_(g" 1 bar"))//HCl_((aq" 0.002M")////HCl_((aq." 0.005M"))//H_(2(g.1"bar"))//Pt^(o+)` The above cell represents similar electrode concentration but the concentration similar electrolytes (HCl) are different. This is electrolyte concentration cell.
