Vertical lines vs commas

Postby Rhea Shah 2F » Sun Mar 08, 2020 8:04 pm

How do you know when to add vertical lines in between the components of a cell diagram, versus when to add commas?

Commas are for when it's the same state (ex. Fe2+ (aq), Fe3+ (aq)), and vertical lines separate different states like g or aq.

Vertical lines in cell diagram represent a change in phase (if there's double vertical lines, then it indicates the presence of a salt bridge). Commas separate two species of the same phase, most of the time this will be ions in aqueous solution.

Use vertical lines between different phases (i.e. s|g|l|aq) and double vertical lines between anode and cathode (anode||cathode). Use commas between molecules of the same phase ( i.e Pt(s), C(s) )

Vertical lines are used to separate species in different states. Commas are used to separate species in the same states.

If they are in the same state, then use commas.
Ex: Fe3+(aq),Fe2+(aq)
If they are different states, then use the vertical lines to indicate that.

A vertical line is for separating components of different states, whereas a comma separates components of the same state.
Ex: (s)|(g) versus (aq),(aq)
