What is the mix ratio for high level chlorine bleach solutions?

Explanation:
Disinfecting with chlorine bleach relies on reaching a specific final concentration of active chlorine. For most household disinfection tasks, the target is about 0.1% free chlorine in the finished solution. Household bleach is typically around 5.25% sodium hypochlorite, so you dilute it quite a bit to get to that 0.1% level. Mixing roughly one third of a cup of bleach with one gallon of water yields a final solution close to 0.1% chlorine. This ratio balances effectiveness with practicality and safety, giving enough disinfecting strength without being overly harsh. The other amounts would not hit that 0.1% target: too little bleach would risk ineffective disinfection, while much more would create a stronger solution that can be corrosive and produce stronger fumes.
