activity coefficient calculator
How do you calculate activity coefficient?
In this activity coefficient equation, the activity coefficient is calculated by multiplying the square root of the ionic strength by the total electric charge of both positive and negatively charged ions in solution (times a constant).
The mean activity coefficient is defiend as follows: γ±=(γ+γ−)1/2.
What is the activity coefficient of 1?
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.
