Purpose: The purpose of this lab is to analyze an unknown and a real world sample of hard water chelated by EDTA by a titrimetric method. In this lab, the indicator is carefully selected to examine and titrate the magnesium and calcium metal ions in each of the four water samples. To calculate the experimental hard water sample’s concentration the average moles was found and then used to find the 95% CI and standard deviation which gives an experimental concentration of Ca2+ in parts per million

Exp. 10 - The Chemistry of Natural Waters David Graves 11/10/15 CHEM 111 Section 104 TA: Lai Shi Group Members: Jasmine Graves, Brad Hensler, Peter Hoholick Introduction Experiment 10: The Chemistry of Natural Waters investigates the topic known as water hardness.

by subtracting the moles of acid given at the start of the experiment, with the moles of acid titrated. Back titration is used for this experiment as Calcium Carbonate is volatile and is an insoluble salt. Therefore they cannot fully dilute with water. As it’s chemical and physical properties are non ideal for a Direct titration, Direct titration cannot be used to determine the Calcium Carbonate content in toothpaste. In Back titration, excess volumes of HCl acids are added to allow for titration

The hardness of water reflects the nature of the geological formation with which it has been in contact. The major portion of total hardness is caused by calcium and magnesium ions and plays role in heart disease in human. The TH of the groundwater was calculated using the formula as given below (Sawyer and McCartly 1967). (1) Table 3: Groundwater classification based on total hardness (Sawyer and Mc Cartly 1967) Total Hardness as CaCO3 (mg/l) Classification Percentage of samples < 75 Soft
