10-3 please!
10 (principal 10-E. (a) Draw the structure of the predominant form species) of 1,3-dihydroxybenzene at pH 9.00 and at pH 11.00 (b) What is the second most prominent species at cach ph (c) Calculate the percentage in the major form at each p 10-E. Draw the structures of the predominant foms of gluta acid and tyrosine at pH 9.0 and pH 10.0. What is the second nost abundant species at each pH? Problems Diprotic Acids and Bases 10-1. Consider HA, the intermediate form of a diprotic acid. K, for this species is 10 4 and K, is 10. Nonetheless, the Ka and K, reac- tions proceed to nearly the same extent when NaHA is dissolved in water. Explairn. 10-2. Write the general structure of an amino acid. Why do some amino acids in Table 10-1 have two pK values and others three? 10-3. Write the chemical reactions whose equilibrium constants are Kbl and Kb2 for the amino acid proline. Find the values of Kb and Kb2. 10-4. Consider the diprotic acid H2A with Ki = 1.00 Ã 10-4 and K2 = 1.00 Ã 10-8 Find the pH and concentrations of HA HAT, and A in (a) 0.100 M H2A: (b) 0.100 M NaHA (c) 0.100 M Na2A. 10-5. We will abbreviate malonic acid, CH2(CO,H)2, as H2M. Fin the pH and concentrations of H2M, HM, and M-in (a) 0.100 HaM: (b)0.100 M NaHM: (c) 0.100 M Na2M.
