Complete the table Buffer System Vol of 10M HCL Vol of 10M c

Complete the table

Buffer System, Vol of .10M HCL, Vol of .10M conjugate base soln., pH, Ka

Ex. HSO4-/SO4^2-, 6.45, 13.55, 2, 1.1*10^-2

From pH 2 to 10.

The choices for the buffer systems are HCO3-/CO3^2-, H2PO4-/HPO4^2-, CH3CO2-, HSO4-/SO4^2-.

**hint \"We are generating the weak acid by adding a strong acid to the conjugate base of a weak acid, H3O^+(aq)+A^--->H2O+HA. Look up the Ka values of the weak acids online.\"

THANK YOU SO MUCH I WILL RATE!! Please please help!

Solution

we can take H2PO4-/HPO4^2- since one of them would balance the acidc sdie and the other will take control of the basic part
