The student diluted a 50.00 ml sample of the original unknown calcium chloride solution to 500.00 ml in a volumetric flask. A student determined the molarity of chloride ion in an unknown calcium chloride solution using anion exchangers in.After passing a 100.00 ml sample of the diluted solution through the anion exchange resin, 42.50 ml of 0.0100M HCL acid were needed to titrate the eluting.
1. Determine the molarity of the chloride ion in the 100.00 ml sample of the diluted solution.
2. Determine the molarity of the chloride ion in the original unknown calcium chloride solution assuming the solution contained only the calcium chloride.
