Suppose you are interested in synthesizing phosphinic acid, H3PO2, a strong reducing agent, from phosphorous acid, H3PO3. In particular, you want to assess the use of oxalic acid in accomplishing this synthesis via the reaction H3PO3 (aq) + H₂C₂O4 (aq) = H3PO₂ (aq) + 2 CO₂ (g) + H₂O (1) (a) Use information from the Table of Standard Reduction Potentials (linked here) to evaluate the standard cell potential (in V) for this reaction. QUESTION 16 Continuation of the previous problem (b) From the result in part (a), determine the equilibrium constant for this reaction.
