aria wants to determine the concentration of Calcium ions in water from their well. She used a 100.0 mL water sample, and its pH was adjusted to 10 and 3 drops of the indicator were added. She used 2.500 mL of 0.09945 M EDTA to reach the endpoint. What is the concentration (mg/L) of calcium ion in the sample? Identify the classification of water given the reference. Reference: 0 to 60 mg/L Ca is classified as soft, 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard
