However, one major concern arising from sodium hypochlorite … Visa mer Stability of the solid Anhydrous sodium hypochlorite can be prepared but, like many hypochlorites, it is highly unstable and decomposes explosively on heating or friction. The decomposition is accelerated by carbon dioxide Visa mer Household bleach sold for use in laundering clothes is a 3–8% solution of sodium hypochlorite at the time of manufacture. Strength varies from one formulation to another and gradually decreases with long storage. Sodium hydroxide is usually … Visa mer It is estimated that there are about 3,300 accidents needing hospital treatment caused by sodium hypochlorite solutions each year in British … Visa mer WebbAt 25 °C, we can correlate whether a solution is acidic, basic, or neutral based off of the measured pH of the solutions: pH = 7 is neutral pH > 7 is basic pH < 7 is acidic However, these relationships are not valid at temperatures outside 25 °C. cid Calculate the pH of a weak acid solution of 0.2 M HOBr, given:
