Cell constant = k x R = 0.146 x 10-3 x 1500 = 0.219 cm-1
Zn (s)|Zn2+ (aq) || Ag+ (aq)| Ag (s) (a) Zn electrode (anode) (b) Ions are carriers of the current in the cell. (c) At anode : Zn(s) → Zn2+ ...
I = 1.5 Ampere Time = 10 x 60s = 600s Q = I x t = 1.5 x 600 = 900 C Cu2+ + 2e- → Cu(s) 2F amount of electricity deposit copper = 63.5 g ...
At anode : Ag(s) → Ag+ + e- At cathode : Ag+ + e- → Ag(s)
Cl2 < MnO-2 < Ce4+
Methane and Ethane.
Anode: Cu → Cu2+ + 2e- Cathode : Cl2 + 2e- → 2Cl-1
The alternating current is used to prevent electrolysis so that the concentration of ions in the solution remains constant.
This is because the overall cell reaction does not involve any ion in the solution whose concentration changes during its life time.
Concentration of sulphuric acid decreases.
Metal having higher oxidation potential will liberate H2 from H2SO4. Thus, A will liberate H2 from H2SO4.
