Final Answer:
3 teaspoons of calcium hypochlorite slurry is added to a full canteen. The correct option is C) 3 teaspoons.
Explanation:
Calcium hypochlorite is typically added to water for disinfection purposes. In a full canteen with a CBRN compatible cap, the amount of calcium hypochlorite slurry needed is typically around 3 teaspoons. This quantity is determined based on the concentration needed for effective disinfection, which is typically around 4 parts per million (ppm) for drinking water. The volume of a canteen is usually around 1 quart or 946 milliliters, and thus, to achieve 4 ppm concentration, around 3 teaspoons of calcium hypochlorite slurry is required.
Calcium hypochlorite is a commonly used disinfectant, particularly in emergency situations or for military purposes where water purification is crucial. The amount needed can vary based on factors such as the concentration of the slurry and the volume of water to be treated. However, in this scenario, considering a standard concentration and canteen size, 3 teaspoons is the typical amount required for effective disinfection.
It's essential to adhere to recommended dosages when using disinfectants like calcium hypochlorite to ensure the water is safe for consumption without causing any adverse health effects. Overdosing can lead to potential health risks, while underdosing may not effectively disinfect the water, leaving it unsafe for consumption. Therefore, understanding the appropriate dosage based on factors like concentration and volume is crucial for ensuring the safety and effectiveness of water treatment processes.
