icture A shows a higher state of entropy (a) Use the letters A and B to identify the acid (A) and base (B) on the left side of the equilibrium arrow and on the right side of the equilibrium arrow. \[ \mathrm{HPO}_{4}^{2-}+\mathrm{H}_{3} \mathrm{O}^{+} \rightleftharpoons \mathrm{H}_{2} \mathrm{PO}_{4}^{-}+\mathrm{H}_{2} \mathrm{O} \] (b) If you added more \( \mathrm{H}_{2} \mathrm{PO}_{4}{ }^{-} \)to this reaction system, would the concentration of \( \mathrm{HPO}_{4}^{2} \) increase or decrease? Explain. (c) If you added more \( \mathrm{HPO}_{4}{ }^{2} \) to this reaction system, would the pH increase or decrease?
