Section 2

Question Answer
-Artificial carbonated waters– Charging waters under pressure with CO2
Carbonated Waters-A type of water in which have been charged with carbon dioxide under pressure while in the earth.
Chalybeate Waters-Contain Fe in solution or suspension and are characterized by ferruginous taste. -Upon exposure to the atmosphere, the iron is usually precipitated as hydroxide or oxide. -Spring and well waters.
Saline Waters-Purgative Waters
Sulfur Waters-Deposits sulfur upon exposure to atmosphere.
Siliceous Waters-Deposits sulfur upon exposure to atmosphere.

Section 3

Question Answer

Section 4

Question Answer
Sterile Water for Injection,Most difficult to prepare. -May be stored in single-dose containers, not larger than 1000-mL size. -Used for extemporaneous compounding (IM and IV)
Bacteriostatic Water for Injection,• Sterile water for injection containing one or more suitable antimicrobial agents.
– Benzyl alcohol
• Used in compatibility with antimicrobials
• Stored in single-dose or in multiple-dose containers, not larger than 30-mL size.
• For extemporaneous parenterals
Water for Injection,-Water purified by distillation -Must pass a pyrogen test. -Intended for use as a solvent for the preparation -of parenteral solutions. -Finished preparation should be sterilized. -Stored at a temp below 4C or above 37C. -Used by large scale pharmaceuticals.
Purified Water,-Water obtained by distillation or by ion exchanged treatment. -For USP test reagents. -Must be labeled to indicate the method of preparation. -Water of choice for extemporaneous compounding.
Water,Official as solvent and is used to make several official solutions, tinctures and extracts.
