Addition of chlorine to water gives both hydrochloric acid (HCl) and hypochlorous acid (HClO): Cl2 + H2O ⇌ HClO + HCl Cl2 + 4 OH ⇌ 2 ClO + 2 H2O + 2 e Cl2 + 2 e ⇌ 2 Cl When acids are added to aqueous salts of hypochlorous acid (such as sodium hypochlorite in commercial bleach solution), the resultant reaction is driven to the left, and chlorine gas is formed. Thus, the formation of stable hypochlorite bleaches is facilitated by dissolving chlorine gas into … WebJan 30, 2024 · Generally, the problem usually gives an initial acid concentration and a \(K_a\) value. From there you are expected to know: How to write the \(K_a\) formula; Set up in an ICE table based on the given information; Solve for the concentration value, x. Use x to find the equilibrium concentration. Use the concentration to find pH.
