Creating a buffer system: 

 

Desired pH = 6.4

What is the best acid to use?

What is the pKa of the acid?

Ratio Ha/A- 

Ratio A-/HA 



I was thinking to use Si(OH)4 because it has a pH of 6.4 but I'm not sure that's right.


edit: Ok, I changed my mind to H2CO3 since its pKa is 6.37? still confused on ratios.
