Cell diagrams

[Janelle2E]

Can someone explain when and why we use Pt(s) in our cell diagram? What does it mean? For example: Pt(s) | H2 (g) | H+ (aq) || Cl2 (g) | Cl- (aq) | Pt (s)

It represents what is used as an electrode to transfer electrons in a galvanic cell. Because the redox reaction doesn't include a solid metal, an inert metal, like Platinum is used as the electrode.

[Kelli Chong [1B]]

Pt(s) plays a role as a conductor in the case that a redox reaction contains no solid metals. Platinum is resistant to oxidation and which is why it is commonly utilized as an electrode.

[Lan Wei 3I]

Pt is necessary when there is no conductor, so Pt must be added to act as the conductor electrode.

[Meylin 1J]

We use a platinum electrode, Pt(s) to catalyze the reaction as platinum facilitates the formation of hydrogen gas without itself being consumed. It is often used when half-reactions involve species that do not interact with other electrode material.
