In a Daniel cell, current flows from cathode to anode outside the cell. If the statement is true enter 1, else enter 0.

Hint:Daniel cell is an example of a galvanic cell. A cell consists of two electrodes cathode and anode. Oxidation takes place at the anode and reduction takes place at the cathode. Current flows in the opposite direction of electron flows.


Complete solution:
As we know that galvanic cells are devices that convert chemical energy into electrical energy. Daniel cell is one of the examples of a galvanic cell.
The Daniel cell consists of an outer copper vessel having a solution of copper sulphate. Inside it is a porous pot containing the zinc strip dipping into a dilute solution of zinc sulphate. The cell is represented as follows:

\[{\text{Zn|ZnS}}{{\text{O}}_{\text{4}}}{\text{||CuS}}{{\text{O}}_{\text{4}}}{\text{|Cu}}\]

In the Daniel cell, the zinc rod acts as the anode while the copper rod acts as a cathode. An anode is an electrode where oxidation takes place while a cathode is an electrode where reduction takes place. So, in the Daniel cell \[{\text{Zn}}\] metal is oxidised into\[{\text{Z}}{{\text{n}}^{{\text{2 + }}}}\]. These ions go into the solution and increase the concentration of \[{\text{ZnS}}{{\text{O}}_{\text{4}}}\]the solution. The electrons that are released travel through an external circuit from zinc electrode to copper electrode that is from anode to cathode. At the copper, electrode electrons reduce \[{\text{C}}{{\text{u}}^{{\text{2 + }}}}\] ions into \[{\text{Cu}}\] and cause a decrease in the concentration of \[{\text{CuS}}{{\text{O}}_{\text{4}}}\] the solution.

Thus, in Daniel cell electrons flow from anode to cathode through the external circuit. As we know that current flows in the opposite direction of electron flow so current flows from cathode to anode outside the cell.

Hence, we can conclude that a given statement is true.

Thus, the correct option is (1).


Note: Loss of electrons is known as oxidation and gain of electrons is known as reduction. The electrode having a greater reduction potential acts as a cathode while the electrode having a lower reduction potential acts as the anode. Electrons flow from anode to cathode while current flow from the cathode to the anode through the external circuit in Daniel cell.
