4/28 CHAPTER 13 AND 14 Note the three types of endpoint detection-Volhard, Adsorption indicator and Mohr. Fig 9-5 shows how mixtures can be determined. Table 13-3 gives some of the possible ions that are determined by this method of titration.

4/30 CHAPTER 13 AND CHAPTER 14 DUE: TO BE assigned. STUDY: p.301: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

What is EDTA? Does the pH of the solution have any changes in what can be titrated with EDTA? See p.298. Is there a universal indicator for EDTA? Especially note section 13B-6. Note the four types of EDTA Titrations. Read about complexometric titrations in a second book. What is hard water? What is the scope of EDTA titrations? What is a masking agent? What is an interfering element?
