Whether you can pour sulfuric acid down the drain depends on the concentration and quantity you have. Can I tell police to wait and call a lawyer when served with a search warrant? Battery acid is a solution of sulfuric acid and water diluted - which means the dilution reduces the strength of the acid. Neutralize the dilute acid. But Sulfuric acid is no more dangerous than gasoline, bleach, or even some drain cleaners (all pretty dangerous by today's standards) if you remember some basic chemistry and safety. You should always wear the appropriate protective equipment to reduce these chances. Sulfuric acid is a very strong chemical that is corrosive. Diluted sulfuric acid with a concentration of 50% or lower can be more easily handled. Most attacks result from jilted lovers or abusive husbands, wives, or just other sick and twisted individuals. If sulfuric acid makes direct contact with the eyes, it cancause permanent blindness. Neutralize spill with sodium bicarbonate/baking soda, When using a neutralizing spill kit, the kits are buffered and will not have a bubbling action. The video describes safe handling and storage of these chemicals, proper loading and off-loading procedures during transportation, and proper use of personal protective equipment and clothing.

Most people prefer disposing of excess sulfuric acid as it poses a serious storage challenge. of the reaction. They probably won't accept it for use, but might dump it into their waste drum for a nominal charge. I would like to know the safest method for neutralizing 70% nitric acid that is used in small amounts of 1-5 ml, for an electronics process in which there will be small traces of silicone and other similar trace materials dissolved into it, to safely contain for proper disposal to not be a risk for acid accidents or fire/explosion risks. . Workers may be harmed from exposure to sulfuric acid. is too late to avoid permanent damage to skin so ''immediate medical attention'' is nothing else than words. You don't need to neutralize small amounts of acid, in fact it is slightly dangerous to do so as it generates a really large amount of heat. The second chemical to consider is calcium carbonate.

Sulfuric acid reacts violently with water, generating much heat. Now, its time to pour out all the acid into your container. How To Dispose Of Battery Acid? With a dibasic acid, like sulfuric (H,SO), still only one molecule of lime is needed to react with one molecule of sulfuric, but two molecules of sodium hy- droxide are necessary. When diluting, the acid should always be added to a large volume of water because the heat released when a small bolus of water is added can cause the water to turn to steam, and the resulting effervescence can splatter the acid. If strong concentrations of gas or solution penetrate clothing, remove clothing and flush the skin with water. If it is concentrated H2SO4 (a thick, syrupy liquid that reacts violently with water giving off enough heat to sometimes induce boiling) it should be cautionsly, slowly, poured over enough crushed ice to result in a room-temperature or lower solution. Pour the acid slowly into the bucket until the fizzing stops, and dispose the solution. Skin or eye contact requires immediate first aid. Leave sink running for 5 min.
