Question

Why is KCl a better salt-bridge than NaCl?

Answer 1

Na+ is higher on the chart and has a larger reduction potential, this is the cathode of the voltage. This means that the K+ is the anode of the cell.

Answer 2

ok @germanphysics

Answer 3

I don't get, why I use for example for a galvanic cell KCl as the saltbridge between the two half cells... I mean, why do I need an anode, when I have a calomel and a silver chloride electrode? Aren't they cathode and anode?

Answer 4

*So I get that I need a electrolyte but I don't get why I prefer KCl :D
