Final answer:
Sodium hypochlorite, a common household bleach, deteriorates quickly when exposed to air, sunlight, and high temperatures, thus the correct answer is D) All of the above. It should be stored in an appropriate manner to maintain its disinfecting and bleaching effectiveness.
Step-by-step explanation:
The stability of sodium hypochlorite, commonly known as household bleach, is affected by various conditions. In response to the multiple-choice question, the correct answer is D) All of the above. Sodium hypochlorite deteriorates quickly when exposed to air, sunlight, and at high temperatures. This decomposition process releases chlorine gas, which is the active disinfecting agent in bleaches. Whether used as a disinfectant or a bleaching agent, it is important to store sodium hypochlorite properly to maintain its effectiveness. As for the stability under different conditions, sodium hypochlorite's decomposition is accelerated by exposure to air and light, and it also breaks down at elevated temperatures. Therefore, it is often packaged in opaque containers to minimize light exposure and is best stored in a cool, ventilated area.
