Need help with this buffer question
A 1.00 liter solution contains 0.38 M hydrofluoric acid and 0.49 M sodium fluoride. If 0.120 moles of barium hydroxide are added to this system, indicate whether the following statements are true or false. (Assume that the volume does not change upon the addition of barium hydroxide.) VA. The number of moles of HF will increase. L B. The number of moles of F will increase. C. The equilibrium concentration of H30* will increase....

Hi,
I need help with this question, thank you!
A 10.00mL sample of 0.1000M an acid (pKg) = 2.89; PK 2 = 5.51) was titated with 0.1526M NaOH. Sketch the graph of pH versus Vook for the titration of this acid through the addition of 25.00mL of NaOH. (3 points) Indicate the numerical pH values for the initial (i.e. before addition of NaOH), half-equivalence, and equivalence points; as well as the pH once the full 25.00ml NaOH has been added....
