The objective of this lab is to determine the hardness of water‚ using the data collected from each titration performed with the unknown sample. Since the hardness of water arises from the presence of metal ions‚ we can use disodium salt of EDTA and the indicator Eriochrome Black T to determine the concentration of M 2+ ( Mg 2+ or Ca 2+) metal ion impurities. Chemical principle or theory involved in this lab: To determine waters hardness we will use a technique called a chelometric titration

Title: Determination of Water Hardness Using a Titrator Purpose: To become familiar with the concept of water hardness‚ practice a titration technique using a titrator‚ and determine the hardness of the local water supply. Procedure: 1. Gather the test tube holder‚ small stopcock‚ 10-mL syringe (titrator)‚ and 2 thick textbooks and the LabPaq box or 5-6 thick textbooks. 2. Remove the plunger from the titrator and place it back in your LabPaq box. 3. Attach the stopcock to the tip of
