Give the chemical composition present in the salt bridge.

What are the functions of a salt bridge in a galvanic cell?

Represent the galvanic cell from following overall cell reaction:

3Ni_(s) + 2Al³⁺ (1 M) → 3Ni²⁺(1 M) + 2Al_(s)

Calculate standard cell potential of following galvanic cell:

Zn/Zn²⁺(1 M) // Pb²⁺(1 M)/Pb. If `"E"_"Pb"^0` = 0.126 V and `"E"_"Zn"^0` = –0.763 V

Calculate the voltage of the cell Sn_(s) / Sn²⁺(0.02 M) // Ag⁺ (0.01 M) / Ag_(s) at 25 °C.

Given: `"E"_"Sn"^circ` = - 0.136, `"E"_"Ag"^circ` = 0.800 V

Calculate `"E"_"cell"^circ` of the following galvanic cell:

Mg_(s) / Mg²⁺(1 M) // Ag⁺ (1 M) / Ag_(s) if `"E"_"Mg"^circ` = – 2.37 V and `"E"_"Ag"^circ` = 0.8 V. Write cell reactions involved in the above cell. Also mention if cell reaction is spontaneous or not.
