EDTA is an organic acid. It is widely used in anaylyzing the hardness (i.e. amount of calcium and magnesium ions) of water. The structure of EDTA. Each molecule of EDTA can react with four molecules of sodium hydroxide (NaOH). Suppose a solution was prepared by dissolving 2.0000g of EDTA in 25.00ml of distilledwater. Molecular weight of EDTA = 292.126g/mol. You may assume the density of the EDTA solution to be 1.000 g/ml.
a) Calculate the molariy of the EDTA solution.
b) Calculate the normality (in context of acid/basereaction) of the EDTA solution.c) Express the concentration in ppm.
