Answer to Question #164700 in General Chemistry for jessica olsziewski

Question

Determine the concentration of chloride ions in a 0.200 M iron (III) chloride solution.

Answer 1

0.2 M FeCl3 is 32.44 g/L. Chemical reaction of dissociation looks like this: FeCl3 = FeCl2- + Cl-. The proportion of chlorine ions for 1 M is: 0.218 (35.5/162.2). Consequently, the concentration of chloride ions in a 0.200 M iron (III) chloride solution is: 7.1 g/L.
