The Total-Interaction Potential Curve

We have now considered briefly the main contributions to the total free energy of interaction between two colloid particles. The most general equation for the total free-energy difference (AG) between particles at infinite separation and at a separation H is obtained by adding these contributions  

In the last two chapters we have explained in general terms some of the main theoretical ideas upon which much of colloid science 

It is important to stress again that what we have done so far is to draw together several aspects of physical chemistry and show how they are relevant to the study of colloids.
