Let me first determine the relationship between ionic strength and the activity coefficient.
00:05
So relation between ionic strength and activity coefficient.
00:36
So that is minus ln, gamma, positive, negative, that is equal to, we have 0 .0.
00:50
Z positive, z negative, a under root i.
00:58
I is the ionic strength, gamma, that is the activity coefficient, a that is the proportionality constant, and z positive, z negative.
01:07
So these are the positive and negative ions charges.
01:12
Okay, the charges present on the positive and negative ions.
01:15
So now you can see that here's what happens that as ionic strength of solution increases so activity coefficient of ions decrease okay so now you can say that hence option b and c are incorrect okay because activities of both ag positive and cl negative neither increase nor remain constant with increase in ionic strength...
