When it comes to comparing the basicity of bleach and ammonia, ammonia is the stronger base. Ammonia (NH3) has a higher pH level than bleach (sodium hypochlorite), indicating its stronger alkaline properties.
Ammonia can readily accept protons (H+ ions) in solution, which is a hallmark of a strong base. This ability allows it to act more effectively in neutralizing acids compared to bleach, which is less basic. While bleach is a strong oxidizer and has disinfecting properties, it does not exhibit the same level of basicity as ammonia.
In conclusion, if you are looking for a substance with stronger basic characteristics, ammonia takes the lead over bleach in that aspect.
