Chlorine is a vital industrial chemical, widely used in the production of various compounds. It plays a crucial role in disinfectants for water treatment, pharmaceuticals, synthetic fibers, and plastics. Despite its importance, chlorine is highly toxic when inhaled in large quantities. Even a healthy individual can suffer from severe respiratory damage, with extreme cases leading to acute pulmonary edema. Inhaling too much chlorine can cause suffocation and even death if not treated promptly. However, the risks associated with chlorine can be effectively managed through proper safety measures and detection systems.
Chlorine gas detectors operate based on electrochemical principles. These devices work by detecting the diffusion of gas molecules, providing reliable and accurate readings. The sensors are designed for personal use, offering excellent performance, ease of operation, and durability. The rugged engineering plastic casing ensures the device can withstand drops and impacts in harsh environments. With a large LCD display, it’s easy to read the data, while its compact and lightweight design makes it convenient to carry in pockets, on belts, or attached to helmets.

**Chlorine Gas Detection Methods**
1. **Simple Method:** First, observe the color—if it’s yellow-green, use wet starch-iodide paper. If the paper turns blue, it indicates the presence of chlorine gas.
2. **Color Observation:** If the gas is present in large amounts and shows a yellow-green color, you can insert a wet red cloth strip into the gas. If the color fades, it may indicate chlorine. However, this method is not foolproof, as other gases also have bleaching properties. If no visible color change occurs, this method becomes unreliable.
3. **Chemical Test:** When the amount of gas is small and the yellow-green color is not visible, you can pass the gas into silver nitrate solution. A white precipitate that does not dissolve in dilute nitric acid confirms the presence of chlorine. However, this method has limitations—gases like sulfur dioxide can also form similar precipitates.
To improve accuracy, an effective approach is to pass the gas into a small amount of purple litmus solution. The solution will first turn red (indicating acidity), then fade (showing bleaching properties). Afterward, adding acidified silver nitrate to the solution will produce an insoluble white precipitate, confirming the presence of chlorine. This two-step process helps avoid confusion with other gases like SOâ‚‚, which lacks the strong oxidizing power needed to fade litmus.
Additionally, nitrogen dioxide (NO₂) and dinitrogen tetroxide (N₂O₄) exist in dynamic equilibrium: 2NO₂ ⇌ N₂O₄. At room temperature, N₂O₄ appears colorless or pale yellow, has a pungent odor, and dissolves in water to form nitric and nitrous acids. It is highly corrosive, with a maximum allowable concentration of 5 ppm in air. Its density is 1.419 at 0°C, melting point -9.3°C, and boiling point 21°C (decomposition). Proper handling and detection are essential to prevent exposure and ensure safety.
