Electrochemistry Doubt (Conductivity)
For weak electrolytes, at infinite dilution, the conductivity of the solution should be very high right?

hmm
interesting
the book also says that conductivity at infinite dilution cannot be obtained by extrapolation of conductivity to zero concentration
the line right before your highlight
yeah
so i'm guessing you can't use the graph as an argument to say that your conductivity should be very high
we don't actually know what type of graph this is
hmmm
i c
also
it makes sense that the conductivity is low
if you take a weak electrolyte and dump it into an ocean (of no other ions)
sure, all the ions are broken apart, but the ocean is huge
that makes sense
you can't exactly use it as a conductor
but in this line it implies the opposite (yellow highlight)
since we don't know what type of graph it is, idt we can extrapolate "lower concentrations" to be near 0 still
for all we know it peaks at 20000
and falls rapidly when it approaches 0
but this is just a guess
that could be the case
so ima let someone else take over
okay
thanks a lot though

This is a better graph
Yess...that makes sense...thank you sooo much

I think this graph is a little bit misleading because of the way it tapers to infinity, right? Mathematically, sure. But actually speaking, weak electrolyte will have a lower conductivity than a strong electrolyte at all points.
ahh oke oke
