Linear Algebra - Linear transformation question. Remember-a common first response to a spill is to try to protect equipment and property, but any real threat to such items will also threaten the persons cleaning up the spill. If you can do so safely, it may be prudent to take interim measures before the hazardous materials response team arrives, such as blocking a spreading spill with absorbents or covering a floor drain with a rubber mat. 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. In other words, bicarbonate is considerably weaker as an acid (about 400 times) than it is as a base, so attempting to neutralize a strong basic solution with it would require an enormous amount. How do you get rid of sulfuric acid smell? Avoid direct contact with such hazards because they spread quickly, are easily absorbed through the skin, and may damage tissue.

Also, the concentration of hydroxide ions in a solution of sodium hydrogen carbonate is much less than in a solution of sodium hydroxide with the same molarity. It will also help you plan for an appropriate response when spills do occur. If a spilled chemical is not hazardous, its cleanup (without the assistance of an emergency response team) is dependent on the ability to control the spill, as well as the availability of sufficient spill control materials (e.g., an absorbent for liquids). Also provide Bases, also called alkaline compounds, have a pH greater than 7. Rise mouth Do not induce vomiting drink sips of water and seek medical attention immediately. Such spills can cause damage and inconvenience, even if they do not present environmental or health risks. amounts of water if chemicals are The ions participating in a neutralization reaction are the H + from the acid and the OH - from the base. All used absorbent materials should be placed in heavy-duty poly bags, which are then sealed, labeled, and disposed through your facility's hazardous waste management program. Use appropriate absorbent material to control the extent of the spill. UNS will neutralize both bases and acids minimizing vapors and solidify the liquid.
