Question- A 1.50L buffer solution is .250 M in HF and .250M in NaF. Calculate the pH of the solution after the addition of .0500 moles of solid NaOH. Assume no volume change upon addition of base. The Ka for HF is 3.5 x 10^-4.
A) 3.34 B) 3.46 C) 3.57 D) 3.63 E) 2.89
Could you also illustrate me the steps to solve the problem? Thanks
I am in hurry anyone is there provide me the answer in quick phase
