What would the pH of a solution containing 3.24g of an acid HX
(Molar Mass of HX = 70.00 g/mol) after the addition of 1.49g of
NaX? Assume no volume change to the solution after the addition of
the NaX. (HX Ka = 1.30E-6)

Remember: if you want to express an answer in scientific
notation, use the letter "E". For example "4.32 x 104"
should be entered as "4.32E4".
What is the pH of a 1.0 L buffer solution containing 0.370 M

Calculate the pH of each solution.
A. A solution containing 0.0133 M maleic acid and 0.0189 M
disodium maleate. The Ka values for maleic acid are 1.20×10−2 (Ka1)
and 5.37×10−7 (Ka2).
