Is the resulting solution acidic, basic, or exactly neutralized? b. What is the pH of the resulting solution? 6. An iron ore sample weighing 0.9132g is dissolved in HCl (aq) , and the iron is obtained as Fe 2+ (aq) . This solution is then titrated with 28.72mL of 0.05051M K 2 Cr 2 O 7(aq) . What is the % Fe by mass in the ore sample? 6Fe 2+ + 14H + + Cr 2 O 7 2-→ 6Fe 3+ + 2Cr 3+ + 7H 2 O 7. Explain why the following reaction cannot occur as written: Fe 3+ (aq) + MnO 4-(aq) + H + (aq) → Mn 2+ (aq) + Fe 2+ (aq) + H 2 O (l)...
