Question

A buffer solution is prepared by adding 30.0g of pure acetic acid to 41.0g of sodium acetate in water, and then diluting the solution to 1.00L. What is the pH of the buffer solution?

Answer 1

mols HAc = grams/molar mass
M HAc = mols/L soln

mols NaAc = grams/molar mass
M NaAc = mols/L soln

pH = pKa for HAc + log(NaAc)/(HAc)
