To determine the concentration of an EDTA solution, the following magnesium(II) solution is prepared: metallic magnesium (m(Mg) = 0.5012 g) is dissolved in dilute sulfuric acid, the resulting solution is poured into a volumetric flask with a volume of 1.000 L and is filled to the graduation mark with water. The titration of an aliquot of magnesium(II) solution with a volume of 25.00 ml consumes (15.22 ml; 15.32 ml; 15.28 ml; 15.24 ml) of EDTA. Calculate the concentration of EDTA solution with accuracy corresponding to the starting data, give confidence interval.
