How do you find the activity coefficient?
Activity coefficients may be determined experimentally by making measurements on non-ideal mixtures.
Use may be made of Raoult's law or Henry's law to provide a value for an ideal mixture against which the experimental value may be compared to obtain the activity coefficient.When activity coefficient is greater than 1?
Conversely, when activity coefficient is greater than 1.0, it implies that molecules have strong repelling force and exhibits positive deviation from Raoult's law.
In this case, lesser energy is needed to separate the constituent molecules.In solutions, the activity coefficient is a measure of how much a solution differs from an ideal solution—i.e., one in which the effectiveness of each molecule is equal to its theoretical effectiveness and thus the activity coefficient would be 1.
What is the activity coefficient of H3O+?
c = a/gamma and in the case of H3O+ (very dilute solution), the activity coefficient gamma is very close to 1.
Finally, the concentration of H3O+ in solution with pH = 7.4 is very close to 10^(7.4) = 39.8 nmol/L.
