Inert Metallic Components

Postby Anthony_Imperial_1G » Sun Feb 12, 2017 10:24 pm

What is the function of inert metallic components such as platinum? How do we know when to use it? Can you give an example if possible? Thanks.

The examples in the book include Pt(s)| H2(g) | H+ (aq) || Zn2+(aq) | Zn(s)

It can be used as an electrode where hydrogen is oxidized in a reaction and cannot be used as an electrode.

You would use a metal component like platinum when none of the reactants or products in a half-reaction are solids. For example, in the half-reaction H2(g) --> 2H+(aq) + 2e- ,
neither side of the reaction (reactants or products) includes a solid, so a platinum electrode is required.

thanks for the great explanation!
