I did an experiment testing the thickness of a salt bridge (made of filter paper soaked in potassium nitrate) on the voltage produced from Zn and Cu half cells.
This is similar to a thread someone made back in 2007.
But I have no idea how to explain my findings or whether the thickness even has an effect. Here are my results:
AVG Voltage
1 layer 7.1
2 layers 8.9
3 layers 9.0
4 layers 9.1
5 layers 9.2
Each strip of filter paper is 6 x 2 cm, stacked on top of each other to create the layers. According to the thread above, it shouldn't have an effect. But how do I attempt to explain the chemistry behind these results?
