In the context of embalming, what is the primary purpose of ammonia in formaldehyde spills?

The primary purpose of ammonia in the context of formaldehyde spills is to neutralize the chemical. Formaldehyde is a potent preservative used in embalming that can be hazardous in case of spills due to its strong fumes and potential health risks. When ammonia is introduced to a formaldehyde spill, it reacts with the formaldehyde to produce less harmful compounds, effectively diminishing its hazardous nature. This process not only helps in addressing safety concerns but also aids in the cleanup process by lessening the lingering effects of formaldehyde.

The other options do not accurately reflect the primary role of ammonia in this scenario. Ammonia does not enhance odor, create a new compound in a beneficial way, or specifically speed up evaporation in this context. Its main function is focused on neutralization, which is crucial in maintaining a safe environment during embalming procedures.
