What process is a standard way to dechlorinate water?

• A. Add sodium thiosulfate
• B. Use municipal water right from the tap
• C. Let water sit for 12 hours
• D. Expose the water to sunlight

Answer: (A)

Removing chlorine from water is essential to protect animal tissues and experimental outcomes. The standard way to do this is to add sodium thiosulfate. It acts as a reducing agent that quickly neutralizes chlorine species, turning them into harmless chloride ions. This method is fast, controllable, and reproducible, so you can dose it based on the chlorine level to ensure consistent dechlorination before using the water in experiments or for animal care. Relying on water straight from the tap leaves chlorine in the water. Letting water sit for a long time can reduce some chlorine, but the process is slow and unpredictable, and chloramines or other reagents may persist or form. Exposing water to sunlight isn’t a reliable or controlled method for removing chlorine.
