FAQs - Sodium Hypochlorite

Is sodium hypochlorite the same as bleach?
Yes, sodium hypochlorite is the active ingredient in bleach. Household bleach typically contains around 5-8% sodium hypochlorite, along with other ingredients such as water and sodium hydroxide.
Can sodium hypochlorite be used to purify water?
Yes, sodium hypochlorite is commonly used in water treatment plants to disinfect drinking water and kill harmful microorganisms such as bacteria and viruses. It is effective in destroying pathogens and ensuring water safety.
What concentration of sodium hypochlorite is used for disinfection purposes?
The concentration of sodium hypochlorite used for disinfection purposes can vary depending on the application. For household cleaning and disinfection, a typical concentration of household bleach is around 5-8% sodium hypochlorite. In water treatment, higher concentrations may be used, typically ranging from 0.5% to 10%.
Can sodium hypochlorite be used to disinfect clothing and laundry?
Yes, sodium hypochlorite can be used as a bleach to disinfect and whiten clothing and laundry. It is effective in removing stains, killing bacteria, and neutralizing odors. However, it's important to follow the instructions on the product label and use the appropriate concentration for the type of fabric being treated.
Does sodium hypochlorite expire?
Sodium hypochlorite gradually loses its potency over time, especially when exposed to light, heat, or air. While it doesn't technically expire, its effectiveness diminishes with prolonged storage. It's best to use fresh bleach for optimal disinfection results, and discard any bleach that has been stored for an extended period or shows signs of degradation.
