When added to water, it forms flocs that capture contaminants, facilitating their removal through sedimentation. This property is particularly important in producing clean drinking water and managing wastewater.
The transformation of benzoic acid into sodium benzoate plays a crucial role in its effectiveness as a preservative. The process involves neutralizing benzoic acid with sodium hydroxide or sodium bicarbonate, resulting in sodium benzoate, a compound with improved solubility in water. This increased solubility is essential because it allows the compound to be effectively utilized in a variety of food products, from soda to bread, enhancing their shelf life and safety.
