AI Thread Summary
If the salt bridge in a galvanic cell is not wetted with KNO3, the cell potential will be negatively affected. The lack of wetting prevents ions from moving across the bridge, disrupting the flow of charge necessary for spontaneous reactions. This results in a decreased measured potential, possibly leading to a negative Ecell value. Additionally, the discussion clarifies that the potential of an open circuit remains positive, emphasizing the role of ions over electrons in this context. Overall, proper wetting of the salt bridge is crucial for maintaining cell potential.

Homework Statement


What will the affect be on the potential of the cell if salt bridge isn't wetted?
If the salt bridge isn't wetted with KNO3 how would it affect the measured potential of the cell2. The attempt at a solution
So I thought that the potenital will be more negative because since the electrons can not go across the bridge this wouldn't be spontaneous and would have a negative Ecell charge?

What is the potential of an open circuit?
 
the potential is positive... ***ions not electrons
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
