Porous Disk vs Salt Bridge

Postby Julia Go 2L » Sat Mar 16, 2019 11:04 pm

Why is the notation for a porous disk a single line (|) but for a salt bridge it is double lines? (||)

Well I would imagine it to be that way because a porous disk is one layer thats touching both solutions while the salt bridge has two sides that touch only their respective part of the cell.

yes, a porous disc is notated by a single line

The reason isn't too important. What's important is that you know that for a galvanic cell, the notation for a porous disk is a single vertical line and the notation for a salt bridge is 2 vertical lines. :)
