Write an equation for the reaction between chlorine and cold NaOH | Cl2 + 2NaOH --> NaCl +NaClO + H20 |
What are the uses of NaCl and NaClO? | Used in bleach. Uses include bleaching paper, textiles, cleaning toilets. |
Write an equation for the reaction between chlorine and drinking water. | Cl2 + H2O --> HCl + HClO |
What is the benefit of the reaction between chlorine and drinking water? | ClO- kills bacteria. |
What are the costs of the reaction between chlorine and drinking water? | Cl is toxic. Cl reacts with organic compounds from plant decomposition to form carcinogenic chlorinated compounds. |
What happens to HClO in sunlight? | It decomposes further to form HCl and 1/2 O2. |
Write an overall equation for the reaction of chlorine and drinking water in sunlight. | 1/2 Cl2 + H20 --> HCl + 1/2 O2 |
