In a hardness of water determination like the one performed in this experiment, it was found that a 25.00-mL sample of water required 12.25mL of 0.0128 M EDTA solution for complete titration. What is the concentration (molarity) of Ca2+ ions in the water sample? What is concentration of CaCO3 (in mg/L) in the water sample? Describe the hardness level of the water using the U.S. government standards.

Rashid has performed titrimetric analysis of antacid tablets which solely contain aluminum hydroxide [Al(OH)3, 78.0 g/mol]. For the sample preparation, he powdered an antacid tablet, dissolved it in 100 mL pre-boiled distilled water, and equally divided the mixture into two Erlenmeyer flasks. Then, he titrated each flask up to the faint pink end point with HCl titrant. Initially, he determined the concentration of the HCl titrant by titrating 10.0 mL of HCl solution with 0.0998M NaOH in duplicate.

In the titration of 25.00 mL of a water sample, it took 20.590 mL of 3.150x 10−3 M EDTA solution to reach the endpoint. The total hardness is due to one or a combination of Ca2+, Mg2+, and Fe2+ in your sample. It is convenient to express this hardness as though it was entirely due to Ca2+. Making this assumption, determine the number of moles of Ca2+ present in the bottled water sample titrated. (enter your answer with 3 significant figures)

PREPARATION OF CHEMICAL REAGENTS As an intern in a research laboratory, you were asked to assist a researcher working on the characterization of pathogens found in a domestic wastewater sample. Specifically, you were tasked to prepare 350mL of a solution that will be used to resuspend and extract specific components from the pelleted slew of pathogens. The extraction solution is composed of 0.75 M phosphate buffer pH 8.0 (Ka2 = 6.2 × 10–8), 1.25 M CaCl2, 0.5% (w/v) SDS (sodium dodecyl sulfate), and 2.5mg per mL proteinase K.
