- Find the full equation and concentration of substances in a redox titration.
A solution containing Co2+ ions of unknown concentration is made. 25mL of this Co2+ solution was measured and was titrated by 0.25M MnO4- solution until equivalence point was reached. An average titre of 16.20 mL MnO4- solution was required. The reaction produces Mn2+ and Co3+ ions.
Write the full redox equation for this reaction and find the concentration of the aqueous Co2+ solution. - Find the full equation and concentration of substances in a redox titration.
A solution containing I- ions of unknown concentration is made. 25mL of this solution is measured precisely and is titrated by 0.18M MnO4- solution until the equivalence point is reached. This is repeated, to find an average titre of 19.55 mL MnO4- solution being needed to completely react the I- ions.
Write the full redox equation for this reaction and find the concentration of the aqueous I- solution.
