18. Calculate the pH of the solution formed when 12.0g of sodium fluoride (0.286mot) Naf, FW- 41.99 is added to 500mL of an O SOOM solution of hydrofluorie neid (HF) We start off with a weak acid in solution. When we add the salt of its conjugate base, we make a buffer solution, and the Na is a spectator ion: The pka for HF is 6.4 x 10-4 (Acid) 0.500M mol Tears 12.0g x -0.286mol [Base] 41.999 0.286mol 500X110-22 -0.572 M Veeln K-(64 x 10-) Complete the problem by calculating the pH of the buffer solution.
