pH 2

The video tutorial covers various types of pH problems, focusing on Henderson Hasselbach problems. It explains phosphate equilibria, the significance of pkas, and how to identify and solve Henderson Hasselbach problems. The tutorial demonstrates solving for diprotic phosphate concentration using the mass balance equation, emphasizing the relationship between pH, pkas, and acid strength.

How do you calculate the concentration of diprotic phosphate given the total phosphate concentration?

Discuss the importance of knowing the predominant species in a solution when solving pH problems.

What steps would you take to solve for the concentration of an unknown species in a Henderson Hasselbalch problem?

What does it mean when the pH is lower than the pKa in terms of acid and base concentrations?
