Suppose potassium phosphate, dibasic, is dissolved in water. Many,many proton transfer reactions begin to happen and come toequilibrium. Write at least 12 balanced equationshappening in this solution that:

Involve a single protontransfer event in each case.

Have different numericalvalues for their equilibrium constants.

Identify each numerical value for each such equilibriumconstant.

Hint: Phosphoric acid hasthree pKa values: 2.3, 6.8, and 12.35.

Hint: There will be phosphoric acid molecules in thesolution

Hint: There will be monobasic phosphate molecular species in thissolution

Hint: There will be tribasic phosphate molecular species in thissolution

How are all these species formed from dibasicphosphate?
