WARNING TM 5-6630-215-12 Induce Vomiting if any of the following chemicals are ingested: Isopropyl Alcohol DPD (Diethyl-P-Phenylene Diamine) Wide Range pH Indicator Solution Arsenite Solution Nessler’s Reagent APHA Sulfaver IV Sodium Hydroxide Standard Solution Chloride Titrant (Silver Nitrate) Phenolphthalein Indicator Solution Maganese Sulfate Solution Sodium Thiosulfate Solution Zinc Reagent Standard Barium Chloride Reagent Reagent “K” (Acetone and Zylenes) Important Refer to the specific “Step-By-Step” instructions relative to accidents as defined in paragraphs covering each specific chemical. a. Acidity Test Kit (fig. 2-5). (1) Acidity is a method of expressing the capacity of water to donate hydrogen ions and gives an indication of the water’s corrosive- ness. The acidity of natural water in normally very low unless strongly acidic industrial water has been introduced. Water is very weak acid. (a) Acidity is caused by carbon dioxide dissolved in water, or tannic acid, or hydrolyzing inorganic salts such as ferrous and/or aluminum sulfate. The presence of mineral acids such as hydrochloric or sulfuric acids from industrial wastes may contibute acidity (paras 2-19f and 2-2 d). (b) Acidity is classified as methyl orange or “free” acidity, which is made up of strong mineral acids such as hydrochloric and sulfuric acids, and phenolphthalein; or “total” acidity, which is the methyl orange acidity plus weak acids such as carbon dioxide, and organic acids. These two classes of acidity may be determined separately. 2-17
