1).If the pH of 1.000 L of HCL is 2.3377, what is the H+? What would the final pH be if 0.17644 g of NaOH were added? Show the reaction between these 2 compounds

2) The pH of solution .1000 M 2,6-Dinitrophenol (acid form, like [HA] is 1.293. If you determine that the phenolate (anion from the weak acid, like [A-]) is 2.41 x 10^-4 M what is the pKa of 2,6-DNP?
