Bleach must be stored away from which of the following?

1. Heat and light

2. Direct sunlight

3. Acids

4. Other disinfectants

The correct answer is: Heat and light

Bleach should be stored away from heat and light to maintain its stability and effectiveness. Exposure to heat can accelerate the decomposition of bleach, reducing its potency and safety for use. Additionally, light can cause chemical changes in bleach, further diminishing its efficacy. Proper storage is crucial for preserving the integrity of bleach solutions, making it essential to keep them in a cool, dark place. While direct sunlight is indeed detrimental as well, heat encompasses a broader range of sources that can lead to degradation. Therefore, the emphasis on heat and light in the context of storing bleach reflects the need to protect chemical products from conditions that could compromise their performance. Storage away from acids, while important, is specifically to prevent chemical reactions that could occur between bleach and acidic substances. Similarly, while bleach should be stored separately from other disinfectants to avoid potential reactions, the broad impact of heat and light on bleach's stability outweighs these considerations.
