they want the activity coefficients for the different ions considering the ionic strength given
so from 10^-4 to 1?
i am using the davies equation to calculate it, so each time I have to change the ionic strength th?

hm no that doesn't seem right. i don't know what they mean by \(10^{-4} \leq 1\), it doesn't make sense.
its \[10^{-4}\le I \le1\]
oh, i thought you typed the same thing twice accidentally. I guess they want it within that range? thats a large range though. I would graph it
on excel of course
we have to calculate and plot it
i guess do a few points for each ion and then plot it
can I show you the full question ? please tell me what I should do
plug it into the formula? \(log\;\gamma=0.5Z^+_0Z^-_0.. etc\) it's kinda weird though because they don't give you the negative counter ion
if I were to do this manually using that given range, how would I approach it?
you would calculate the coefficient for several points (ionic strengths) do 3 or 4, then plot these. Activity coefficient on the y axis and ionic strength on the x axis (although you can do on which every way you want)
it's much easier if you do it in excel though
yes, that is where I am having problem.
like that range is between 10^-4 to 1 right?
yep thats the range of "I" they gave
how would I calculte that in excel though?
if I do it manually then can I chose to do something like I= 10^-4,10^-3, 10^-2 and 10^-1?
yeah thats fine
for excel you need the x data point and the y data point the x you can just make up: 10^4, 10^3 then for the y you have to use the result from the equation, so you would type up the equation and use the x data points, then fill it. If you're not familiar with excel trying it this way might take you awhile
okay, thank you so much.
no problem, good luck!
thanks :-)
