Equilibrium Potential of a Solution When it Contains an Ampholyte

7 Equilibrium Potential of a Solution When it Contains an Ampholyte 

An example of an equilibrium potential of a solution when it contains an ampholyte is provided by the reaction of the hypovanadous ion V + with the vanadyl ion VO + to give the vanadate ion V + according to 

From a general standpoint, let s consider the following two couples  

Let s also consider the mixture of both forms Redi and 0x2 in any proportion. The redox reaction that occurs between them is 

The calculation of the solution equilibrium potential is achieved after resolving the system of the following relations
