Addition of brine to a solution of potash soap, on the other hand, merely results in double decomposition, soda soap and potassium chloride being formed, thus:-- C_{17}H_{35}COOK + NaCl = C_{17}H_{35}COONa + KCl potassium sodium sodium potassium stearate chloride stearate chloride The solubility of the different soaps in salt solution varies very considerably.

The temperature 92° is, therefore, a transition point at which the reversible reaction-- CuK_{2}Cl_{4},2H_{2}O CuKCl_{3} + KCl + 2H_{2}O takes place.

The retroflex portion of the curve represents solutions in equilibrium with carnallite and potassium chloride, but in which the ratio MgCl_{2} : KCl is greater than in the double salt.

Further, reference has already been made to the fact that all points of the carnallite area correspond to solutions in equilibrium with carnallite, but in which the ratio of MgCl_{2} to KCl is greater than in the double salt.

Having determined the equilibrium conditions for the different salts, it is then possible to construct a model similar to that for MgCl_{2}--KCl--H_{2}O or for FeCl_{3}--HCl--H_{2}O, from which it will be possible to determine the limits of stability of the different salts, and to predict what will occur when we bring the salts in contact with solutions of nitric acid of different concentrations and at different temperatures.
