Such consideration should focus on reducing the likelihood of spills, as well as minimizing spill damage. Promptly place cleanup wastes in an appropriate hazardous waste receptacle. Baking soda is sodium bicarbonate, which requires an acid and a liquid to become activated and help baked goods rise. This may result in gas or bloating, especially if you ingest the mixture before all the gas has escaped (3). In the case of sodium bicarbonate reacting with sodium hydroxide, hydrogen ions formed by the dissociation of bicarbonate are removed by reaction with hydroxide ions to form water, causing the equilibrium to shift to favor greater dissociation of bicarbonate, driving the reaction to completion. At worst, a spill can cause bodily harm or property damage. Contact your environmental health and safety officer for guidance in packaging and labeling cleanup residues. This question focuses on Learning Objective 3: Describe various forms and uses of safety. Normal eyeglasses may be worn to substitute for safety goggles. This breakdown makes a solution alkaline, meaning it is able to neutralize acid.
