What is a significant advantage of using sodium hypochlorite in water treatment?

Sodium hypochlorite is widely used in water treatment primarily due to its stability compared to chlorine gas. Chlorine gas can be hazardous as it requires special handling and storage considerations, being prone to volatility and requiring stringent safety protocols. In contrast, sodium hypochlorite is a liquid that is easier to transport and handle, making it a safer option for water treatment processes.

Furthermore, the storage conditions for sodium hypochlorite are generally less demanding than for chlorine gas, as it can be kept in standard containers and does not require pressurized systems. This contributes to its reputation as a stable disinfectant and suggests that it can provide a more consistently reliable source of chlorine for water treatment, leading to efficient and effective disinfection.

The other options do not align with the primary advantages of sodium hypochlorite in water treatment, emphasizing why its stability is recognized as a significant benefit.
