The reactions are as follows: Base spills: H2SO4 + 2NaOH Na2SO4 + 2H2O 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. Additional protective equipment may be required for spills that present special hazards (such as corrosive or reactive spills or spills that have a splash potential). The general reaction results in a salt, carbon dioxide gas, and water. The cookie is used to store the user consent for the cookies in the category "Analytics". Add absorbents to the spill, working from the spill's outer edges toward the center. I would like to ask, for me it appears the current answer attempts to find how much bicarb is needed for the pH to be 7, whereas for the NaOH + NaHCO3 reaction, the salt will be basic, meaning, more bicarb will be needed for a neutral pH than just what is required to complete the reaction, hence the calculation. When mixed with acids, is soluble and may become gummy or create a slurry, making it difficult to clean up. I am going to argue that the currently-accepted answer is incorrect. FEEDBACK If handled improperly, a spill can seriously disrupt your activities and the work of your colleagues.
