O = HOCl (hypochlorous acid) + HCl (hydrochloric) When a hypochlorite is added to water, the reaction forms hypochlorite ion and hydroxide: NaOCl (sodium hypochlorite) + H 2 O = OCl¯ (hypochlorite ion) + OH (hydroxide) Hypochlorous acid and hypochlorite … While sodium hypochlorite is used, hydrochloric acid (HCl) is used to lower the pH. We report a case of asthma, persisting 2 years after the inhalation of a mixture of sodium hypochlorite and hydrochloric acid… The pH of the water determines how much hypochlorous acid is formed. Existence of respiratory sequelae is debated. Chlorine gas inhalation can lead to temporary mucous membrane irritation, pulmonary edema, and transient bronchospasm. Sodium hypochlorite can be used in place of the gaseous chlorine to generate chlorine dioxide. The mixture of sodium peroxide (Na 2 O 2) and hydrochloric acid, which react to produce sodium hypochlorite. A 2008 study indicated that sodium hypochlorite … Less harmful gasses are produced when sulfuric acid … Sulfuric acid (H 2 SO 4) can be used as an alternative for acetic acid. However, an excess of chlorine is often used to lower the pH to the required minimum of 3.5 and to drive the reaction to completion. Sodium Hypochlorite; advantages Disinfection with sodium hypochlorite … Sodium hypochlorite solutions, such as liquid bleach, may release toxic chlorine gas when heated above 35 °C or mixed with an acid, such as hydrochloric acid or vinegar. This process requires the addition of sulfuric or hydrochloric acid … is also termed as oxone.
