Calculate the theoretical ph of 0.250 m weak acid ha., Ask an Expert

Academics

1. Calculate the theoretical pH of 0.250 M weak acid, HA. Calculate the theoretical pH of a

2.5 x 10-3 M weak acid, HA, that has a Ka value of 1.2 x 10-4. What happens to % ionization of the weak acid as you dilute the acid?

1. What would be the theoretical pH of a buffer prepared by mixing 5.00 mL of 4.0 M formic acid with 1.50 g of sodium formate and the total volume made up to 100 mL.

The Ka of HCO2H is 1.8 x 10-4.
