Homework Help: chemistry

Posted by jed on Monday, January 26, 2009 at 8:22am.

Hi. We did an experiment on Quantitatve Determintion of Total Hardness in Drinking water by Complexometric EDTA Titration and I have a lot of questions.

1. What is the concept of complexometric titration and water hardness? (Why is it expressed in ppm CaCO3?)

2. Why is EDTA use as complexing agent and titrant?

3. Why is EBT use as an indicator? What is the significance of adding MgCl26H2O crystals to the titrant?

4. What are the other applications of EDTA complexation?

5. What is the rationale behind performing the analysis of Ca and Mg at pH 10?

thank you so much for your time.
