Question

Concentration of FeSCN2+ = 0.0565 mol/L

11. The volume of the cyanide solution that was found at the scene was 20 mL. Based on the calculated concentration of FeSCN2+ in the unknown solution, determine the concentration of potassium cyanide, KCN, in the original poison solution. Show all your Hint: One mole of KCN will produce one mole of FeSCN*. Assume that all of the KCN in the poisoned solution reacted to form FeSCN2+. Assume that the 20 mL of original solution was not diluted during the reaction to form FeSCN+ and that the sample you received in lab was also undiluted. The molecular weight of FeSCN+ is 114 g/mol. The molecular weight of KCN is 65 g/mol
