Question
Write the chemical equations representing the stepwise, partial ionization reactions of malic add, a diprotic acid with a chemical formula of H_2C_4H_4O_5. The acidic hydrogens are shown at the front of the formula. Include water and states of matter in your equations. Write balanced chemical equations for the two ionization steps of selenic acid, H_2SeO_4. The first ionization is complete; the second reaches an equilibrium mixture of reactants and products. Use the simplified equations (omit H_2O from the reactants).Explanation / Answer
1)
1) H2C4H4O5 (aq) + H2O(l) <---------------> H3O+(aq) + HC4H4O5-(aq)
2) HC4H4O5-(aq) + H2O(l) <-----------------> H3O+(aq) + C4H4O5-2(aq)
2)
1) H2SeO4(aq) ------------> H+(aq) + HSeO4-(aq)
2) HSeO4-(aq) <-----------------> H+(aq) + SeO4-2(aq)
