1
Q
activity
A
The value that replaces concentration in a thermodynamically correct equilibrium expression. [X]Activity coefficient
2
Q
activity coefficient
A
The number by which the concentration must be multiplied to give activity.
3
Q
charge balance
A
A statement that the sum of all positive charge in solution equals the magnitude of the sum of all negative charge in solution.
4
Q
extended Debye-Huckel equation
A
Gives the activity coefficient as a function of ionic strength.
5
Q
ionic atomsphere
A
The region of solution around an ion or a charged particle. It contains an excess of oppositely charged ions.
6
Q
mass balance
A
A statement that the sum of the moles of any element in all of its forms in a solution must equal the moles of that element delivered to the solution.
