Apparatus:

• 205945 - Pipet, 25 mL
• 205700 - Buret, 25 mL
• 205982 - Erlenmeyer Flask, 250 mL
• 205402 - Beaker, 250 mL
• pH meter
• 205943 - Pipet, 10 Ml

 Reagents:

• Standard Sulfuric Acid 1.0 N
• Alizarin yellow, 1 % in isopropanol

Procedure:

• Obtain a sample from the tank and allow to cool to room temperature.
• Pipet 25 mL of the sample into a 250 mL volumetric flask and dilute to the mark.
• Mix well and pipet 20 mL of the diluted sample into a 250 mL beaker.Add 100 mL DI water.
• Titrate to pH 11.4 with 1.0 N Sulfuric Acid, or to the Alizarin Yellow indicator end point (4 drops - color change pink to yellow).
