Question
For problem 5, the density of the sample is 0.9977 g/ml. and the molar mass of calcium carbonate is 100.0 g/mol. 5. As described in Topic 2 in the lab manual, the hardness of water is expressed in terms of amount of calcium carbonate according to the ppm expression. Calculate the mass of calcium carbonate present in a 50.00 mL sample of an aqueous calcium carbonate standard, assuming the standard is known to have a hardness of 75.0 ppm (hardness du to CaCO;). a. b. Calculate the number of moles of calcium ions present in this 50.00 mL sample of aqueous calcium carbonate standard. C. The 50.00 mL sample (at pH 10) was titrated with a 0.00500 M EDTA solution, Write the balance net ionic equation for the reaction of EDTA“ with a calcium ion. Calculate the number of moles of EDTA“ needed to completely react with calcium ions in the sample. What volume (in milliliters) of EDTA solution would be needed to reach the equivalence point?
