| Question | Answer | Explanation |
| With respect to A the metal is | Al and it is Anode | Left hand side eletrode is anode and it will undergo oxidation. |
| With respect to B the metal is | Sn and it is Cathode | Right hand side eletrode is cathode and it will undergo reduction |
| With respect to C the solution is | Al3+ | Because the anode is Al dipped in its own salt |
| With respect to D the solution is | Sn2+ | Because the cathode is Sn dipped in its own salt |
| With respect to E is called | Salt bridge | Salt bridge is directly connected to the two solutions without any wire as medium. |
| With respect to F there is usually---- to measure the current. | Voltmeter | Since the cell is galvanic cell, it will generate current in Volts. It has to be measured by Voltmeter. Also, a hint is given:"to measure the current". A galvanic cell is otherwise called as Voltaic cell |
| E0 of the cell | +1.522 V |
E0Al3+/Al = -1.662V E0Sn2+/Sn = -0.14 V Ecell = ER -EL = -0.14 -(-1.662) = -0.14 + 1.662 = 1.522 V |
for sentence 1 and 2 these are the options (respect to a and b. for sentnece...
