Do all galvanic cell produce same voltage?

Answer:

No

Step-by-step explanation:

A galvanic cell is an electrochemical cell that converts chemical energy into electrical energy. The chemical energy is transformed/converted through a series of spontaneous redox reactions in the cell.

A galvanic cell has two electrode (the anode and the cathode) immersed in an electrolyte. Electrolyte is a liquid that allows the flow of electricity to pass through it. Examples include aqueous NaCl solution, HCl and HNO₃. These electrolytes have different capacities (based on there ability to dissociate into ions). The production of the voltage in a cell is dependent on the choice of electrolyte (its ability to dissociate) and the type of electrodes used (this is because some electrodes are better conductors of electricity than the others). Hence, different electrochemical set-up/reaction (in this case galvanic cell) will produce different voltage.

No, not all galvanic cells produce the same voltage. Different reactions=different free energy change=different cell voltage.
