Recently I did an experiment on the effect of the concentration of the salt bridge solution. I used Potassium Nitrate 4M as the solution, and diluted it to 2M, 1M, 0.5M and 0.25M and tested the voltage over time. The voltage increased as the concentration decreased, which I believe to be incorrect. If anyone could confirm the effect for me, that'd be great.

Can you explain why you think the salt bridge would increase voltage at higher concentrations?  What does it do, and how does it do it?
