During a redox titration, it was found that 10.0 mL samples of a 0.825 mol/L CrCl2 solution react... ed stoichiometrically with an average 14.8 mL of K2Cr2O7 acidic solution. Chromium (II) ions from the chloride became Cr (III). a) With assistance of the Table, write the two half-reactions (in ionic form) and then the complete balanced redox reaction involved in this titration. (Make sure you distinguish the two types of chromium ions) b) With the previous information and showing all formulas and dimensional analysis, calculate the molar concentration of potassium dichromate used as a titrant and report it with the correct number of significant digits.
