Avoid contact with EYE / Hand and other CHEMICALS and Gases.
 

For determination of Hydroxide alkalinity only, barium chloride is added prior to titration to precipitate the carbonate ions.  Titration is then taken only to the phenolphthalein end point.  A pH meter may be used instead of the indicators to determine the end points of the titration.

REAGENT & APPARATUS:

Before Sampling all PRECAUTION should be taken :::

Toxic effects of Hydrazine ( which is collected in sample ) is a severe skin and mucous membrane irritant in humans; in animals.In humans, the vapor is immediately irritating to the nose and throat and causes dizziness and nausea; itching, burning, and swelling of the eyes develop over a period of several hours. Severe exposures of the eyes to the vapors causes temporary blindness lasting for about 24 hours. Recurrent exposure to hydrazine hydrate has been reported to cause contact dermatitis of the hands without systemic intoxication. In humans, hydrazine is absorbed through the skin, by inhalation, and orally; systemic effects include weight loss, weakness, vomiting, excited behavior, and convulsions; the chief histologic findings are fatty degeneration of the liver and nephritis.
