... of unknown acid100ml Normality of NaOH.05 Milliliters of NaOH at eq. Pt. 26.25 Normality of unknown acid.013 Review Questions: 1)Bronsted-Lowry acid – donates H+ Base – accepts H+ 3) The pH at the equivalence point isn’t always 7 because if there is a weak acid and a strong base, the resulting equivalence point will be more basic and visa versa. 4) The pKa of an acid whose Ka is 2.4 X 10 ^ -8 is 7.6. 6) A buffer solution is a solution containing a weak acid or base and its salt, which when excess acid/base is added the solution’s pH holds fairly constant. For example; HOAC & OAC- 7) Ka/H+ = salt/acid x / (10^(-5.8)) = 1/1 x / Ka = 1.58 X 10 ^ -6 8)NbVb = moles = given grams/molmass .0315 x .0995 = .00313 = .18/x = 57.43 grams 9) Ka/H+ = 1/1 H + = 1.85 X 10 ^ -5 at half equiv.
