Heat on water bath until the chloroform has been removed. Cool and dilute to 500 mL with distilled water and proceed to distillation as in (A). 2. Extraction and color development Take 500 mL of the distillate or a suitable portion containing more than 50 mg phenol and dilute to 500 mL in 1 L beaker. Take 500 mL distilled water blank and a series of 500 mL phenol standards containing 5, 10, 20, 30, 40, and 50 mg phenol, in respective beakers. 1 with 10 mL phosphate buffer. 0 mL potassium ferricyanide; again, mix well and let the color develop for 15 min.

Draw off the aqueous layer into another separating funnel and again extract with 50 mL of petroleum ether. Combine the extracts in a beaker and pass them through the Whatman filter paper No. 1 containing sodium sulfate in its cone and moistened with the solvent, collected into evaporating dish, and keep it on a water bath. Dry the outside, cool, and weigh (W2). The difference in weight is the amount of oil present in the aliquot of the sample. 8 Chloride Natural water, industrial wastewater, and even some surface water contain chlorides in varying amounts.

Hydroxyl ions present in a sample as a result of dissociation or hydrolysis of solutes react with additions of standard acid. Alkalinity thus depends on the end point pH used. Titrate at room temperature with a properly calibrated pH meter or electrically operated titrator or use color indicators. Apparatuses a. 250 mL measuring cylinder b. 250 mL conical flask c. Burette Reagents i. 1 N): take 3 mL concentrated H2SO4 and dilute to 1 L with distilled water. ii. 2 g (dry) and dilute up to 1 L with distilled water.
