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.

WebFeb 3, 2024 · The value of K a is used to calculate the pH of weak acids. The pK a value is used to choose a buffer when needed. Choosing an acid or base where pK a is close to the pH needed gives the best results. Relating pH, Ka, and pKa pH, Ka, and pKa are all related to each other. For an acid HA: K a = [H + ] [A -] / [HA] pK a = - log K a WebNov 25, 2024 · I have 200mL of HClO 0,64M. I mix it with 0,1mol of NaClO. How should I calculate the pH? My question is about this: should I keep attention about changes made to the solution volume after adding NaClO? So far this is what I've done.
