When writing the cell diagram, how do you know which phase to write?

Normally you can tell the phases of the reactants and products from the equation given. For example if there was the reduction of Co2+(aq) to Co(s) then Co would be a solid and Co2+ would be aqueous. Then, in the cell diagram, you separate phases in contact by a single line (|) and sides of the galvanic cell by double lines (||)

The phases are usually given in the equation. You can use those same ones in writing the cell diagram.

If the reactant or product is an ion, it is usually aqueous, but if it has no charge then it is in its standard state (solid or gas).

Yes, often by losing charge and converting to the solid phase, you can see the accumulation of the solid metal on the electron. The charge ion is usually able to dissolve in the water.
