You have a sample of approximately 100 mg/L of calcium carbonate and the standardized EDTA has a concentration of 0.00085 M. If you only want to spend approximately 15 mL of the titrant and add 25 mL of sample in the Erlenmeyer flask, can you use it or should you dilute it? the sample?, how much? Solution: No, 29 mL would be needed to titrate the sample, you must dilute it approximately 1: 2. Taking, for example, 25 mL of sample and making up to 50 mL.

The concentration of a solution of EDTA was determined by standardizing against a solution of Ca2+ prepared from the primary standard CaCO3. A 0.4302g sample of CaCO3 was transferred to a 60mL volumetric flask, dissolved using a minimum of 6 M HCl solution, and diluted to volume. A 44mL portion of this solution was transferred into a 250-mL Erlenmeyer flask and the pH adjusted by adding 5 mL of a pH 10 NH3-NH4 L buffer containing a small amount of Mg2+ EDTA. After adding calmagite as a visual indicator, the solution was titrated with the EDTA, requiring 632mL to reach the end point. Calculate the molar concentration of the titrant
