A chemist titrates 30.0 mL of a sample solution containing CI-(aq) ions with a 0.0489 mol/L KMNO4(aq) solution. The light purple-coloured end point is attained after the addition of 22.5 ml of the KMNO4(aq) (solution in the buret). The KMnO4faq) dissolve, and the balanced net ionic equation is: 2MNO4 (aq) + 10CI-(aq) + 16H*(aq) → 2Mn²+ (aq) + 5C12(g) + 8H2O( 2 ) The molar concentration of CI-(aq) ions in the sample solution is: a. 0.0489 mol/L 0.300 mol/L С. b. 0.225 mol/L d. 0.183 mol/L
