takes place. Further show: (i) Which of the electrode is negatively charged? (ii) The carriers of the current in the cell. (iii) Individual reaction at each electrode.Solution: It is an electrochemical cell named after the inventors Luigi Galvani and Alessandro Volta, respectively, in which an electric current is generated through spontaneous reactions.
The galvanic cell in which the given reaction takes place is depicted as:
![\[Z n_{(s)}\left|Z n_{(a q)}^{2+} \| A g_{(a q)}^{+}\right| A g_{(s)}\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-62a219fd562302e07da211b3d5e456ef_l3.png "Rendered by QuickLaTeX.com")
(i) The negatively charged electrode is the Zn electrode (anode)
(ii)In the cell, ions serve as current carriers. Current goes from silver in the external circuit to zinc in the internal circuit.
(iii) Reaction at the anode is given by:
![\[Z n_{(s)} \rightarrow Z n_{(a q)}^{2+}+2 e^{-}\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-565aa04ec5d306cb318ea9f0509b567b_l3.png "Rendered by QuickLaTeX.com")
Reaction at the anode is given by:
![\[A g_{(a q)}^{+}+e^{-} \rightarrow A g_{(s)}\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-2520c392b8a4b3d9ac13365648c254f1_l3.png "Rendered by QuickLaTeX.com")
