Question

34.) 8 points Monohydrogen e is an amphoteric substance. Illustrate these propertied by writing the appropriate Ka Ks equations and corresponding equilibrium 35.) 6 points Complete 1 of the following 2 questions A. Determine the equilibrium constant for the system N042NO2 at 0 M what is the 2.48x10AM [N01-141 concentrations are shown here: [N2Oa] Kp at this temperature?CNa0 alyio -4 weak acid when dissolved in water is 0.66% dissociated and produces a solution with a pH of 3.04. Calculate the Ka of the acid.

Explanation / Answer

According to chegg rules we have to answer only first one problem

Mono hydrogen phosphate; HPO42- as acid:

HPO42- + H2O <== > PO43- + H3O+

Ka = [PO43-] [H3O+] / [HPO42-]

Mono hydrogen phosphate; HPO42- as base:

HPO42- + H2O <== > H 2PO4- + OH-

Kb = [H 2PO4-] [OH- ] / [HPO42-]
