Anything with a pH of 11 can kill grass and other plants, the majority of which need a mid-range soil pH: around 7.0. Vapors can cause serious discomfort or even acute distress requiring medical attention. Sodium Hypochlorite Poisoning is the accidental or intentional intake (swallowing, breathing-in, or skin contact) of any product containing the compound. The molar mass of sodium hypochlorite is 74.44 g/mol. Sodium hypochlorite in 0.5% w/v solution is called Dakin's solution, and is used as an antiseptic to clean infected topical wounds. Safety is a primary concern at manufacturing plants because of the presence of volatile chlorine gas. Low levels of exposure may result in eye and oral mucous membrane irritation, dizziness, and nausea – while exposure to high levels may be fatal. The Benefits of Bleach (Sodium Hypochlorite) While bleach or sodium hypochlorite can be hazardous, when used properly, it can make the world at large a much healthier place. Scheele, a Swedish chemist, is generally credited with discovering chlorine in 1774. ("Cornell University", 1986) It's chemical formula is NaOCl, which indicates that it needs one Sodium atom, one Oxygen atom, and one Chlorine atom to create this compound. It is also used as an oxidizing agent for organic products. Bleach is not stable at dilute concentration. In the bleach manufacturing facility, the final sodium hypochlorite solution is put through a series of filters to extract any left-over impurities.
