What type of mixture can neutralize formaldehyde?

The correct choice is ammonia with water because ammonia is known to effectively neutralize formaldehyde. When ammonia is mixed with water, it creates an alkaline solution that can interact with formaldehyde, leading to the formation of less harmful compounds. This property makes ammonia a suitable agent in both industrial and laboratory settings for disinfecting and neutralizing formaldehyde fumes.

Other combinations, while they might have some cleaning properties, do not specifically neutralize formaldehyde in the same effective manner. For instance, vinegar and water, though often used as a cleaning agent, primarily contain acetic acid, which doesn't interact effectively with formaldehyde. Rubbing alcohol and water can be useful for disinfection but do not neutralize formaldehyde. Similarly, hydrogen peroxide and water is known for its oxidizing properties and can act as a disinfectant but lacks the specific capability to neutralize formaldehyde effectively. Thus, ammonia with water stands out as the most effective choice for neutralizing formaldehyde.
