What substance increases water pH, making it a poor option as a water sanitizer?

1. Chlorine

2. Ozone

3. Sodium hypochlorite

4. Hydrogen peroxide

The correct answer is: Sodium hypochlorite

Sodium hypochlorite is a compound that, when dissolved in water, can increase the pH level of the water. At higher pH levels, the effectiveness of water sanitizers can diminish, as many pathogens are less susceptible to disinfection in alkaline conditions. This makes sodium hypochlorite less effective as a water sanitizer in situations where maintaining a lower pH is critical for optimal disinfection. In contrast, chlorine, ozone, and hydrogen peroxide are often favored as sanitizers precisely because they maintain efficiency across a wider range of pH levels and are effective at lower pH values, allowing them to effectively kill harmful microorganisms without compromising water quality. Therefore, sodium hypochlorite’s ability to elevate pH renders it a poor option for someone looking to sanitize water effectively.
