Porous Disk and Salt Bridge

[305174946]

So I understand that both the Porous Disk and Salt Bridge are used to transfer ions but is one more efficient than the other? If so, why? Just curious

[eden tefera 2B]

I don't believe that one is more efficient than the other.

[Swetha Ampabathina1I]

Since they both serve the same purpose, I don't think either one is more efficient than the other.

[Ahmed Mahmood 4D]

They both serve the same purpose and thus have essentially no reasonable difference in this class.

[Maya Beal Dis 1D]

In lecture didn't Lavelle say that the voltage is typically lower with the porous disk in a concentration cell?

[Nathan Rothschild_2D]

Don't the do the same thing, but in different situations so how could you compare their efficiency. Porous disks are for 2 of the same solutions that are different molarity or am I misunderstanding what they are?

[Asha Agarwal 1E]

I think they both serve the same purpose of reducing charge buildup so one is not much more effective than the other.

[Zoe Gleason 4F]

They have the same function, so one will not be more efficient than the other.

[Diana Andrade_4F]

Since they ultimately have the same function, I believe that one isn't more efficient than the other

[Omar Selim 1D]

I don't believe there is a difference in efficiency. They serve the same purpose in balancing charges and the distribution of ions.

[Jialun Chen 4F]

I agree with the comments above. There's not a difference in efficiency between the two based on what I know of.

[AGaeta_2C]

I think especially for the purpose for this class, there is no difference in efficiency between the two.

For this class though, we mostly use the salt bridge. Are there any homework problems in which we use the porous disk ?

[Ruby Richter 2L]

If there is no difference in efficiency then when would you use a porous disk instead of a salt bridge?
