For the first part, you will:
Prepare and standardize EDTA solution and use the solution to titrate and determine the calcium ions concentration in ONE unknown calcium solution provided by the TA. You must keep your standardized EDTA to complete the project next week.
Here is some specific information you need to include in the Methods and Procedures section of the pre-lab plan submission rubric below.
- What is water hardness? What metal ions are we looking for?
- What are some common techniques used for water sample analysis? List at least two.
- What is the structure of EDTA and why are we using EDTA in this lab?
- What metals can EDTA bind to?
