Calculate the expected buffer capacity of the phosphate buffer based on the number of moles of HPO4 2- (Hint: You know the concentration and the volume). In other words, how many moles are needed to break the buffer? Does the measured buffer capacity of the phosphate buffer meet your expectations? Explain. The concentration of HPO4 2- is 0.050M, and the volume is 100 mL (0.1 L). I got 0.005 mol HPO4 2-. How do I find the buffer capacity from here?
