1–4.Plenum Press: New York, 1976. asked by Rossel on October 16, 2007; chemistry - (Dr. Bob222) Explain why malonic acid’s first proton is a stronger acid than acetic acid (pKa = 4.75). The pKa for the first proton lost is 2.83 and the pKa for the second proton lost is 5.69. PubChem Substance ID 57651938. Explain clearly why the first pKa of malonic acid is lower than the first pKa of succinic . HAsO 4 2– 3.2×10 –12. (4) a. Beilstein/REAXYS Number 3917013 . Malonic acid and succinic acid each have two different pKa values. NACRES NA.22 Malonic acid, HO2CCH2CO2H is a diprotic acid. Write out the two dissociation equations for malonic acid and identify the conjugate base in each case. An
