Apr 6, 2015. It is usually not a chemical reaction. Bubbles are often the result of agitation of toilet water or cleaning chemicals/detergents in the toilet. If the bubbles persist in foamy consistency even in standing water, it means there might be some denatured proteins in urine.
Fumes in air. Reacts violently with water to form hydrogen fluoride and sulfuric acid mist. Based on a scenario where the chemical is spilled into an excess of water (at least 5 fold excess of water), half of the maximum theoretical yield of Hydrogen Fluoride gas will be created in 0.12 minutes.eactive Groups-List of reactive groups that the chemical is assigned to, based on its known chemistry. Reactive groups are categories of chemicals that react in similar ways because their chemical structures are similar. Reactive groups are used to predict reactivity when you add a chemical to MyChemicals.
