Calculations are based off of my data table.  I'm not sure how to answer the questions. 1.Based on the results of your experiment, do you have hard or soft water? Does this match the data for your area? Briefly explain your answer. 2.How much calcium would you ingest by drinking one 8 oz glass of your tap water? Show all calculations. 3.What percentage of the recommended daily dose of calcium (1,150 mg/day) does 1.0 L of your water provide? Show all calculations. 4. A complexometric titration can also be used to determine the amount of calcium in milk. The calcium concentration in milk is typically 1,200 mg/L. How would you alter the procedure used in this experiment to determine milk’s calcium content?
