It needs to be flushed with a lot of water ASAP, then baking soda can be used to help get in and finish neutralizing the acid. Re: Neutralizing 98% Sulfuric Acid. Keep a source of fresh water nearby to use in case of any accidental splashes or spills. 3. The battery in the system is like a car battery, but it's the kind where you initially add sulfuric acid to, and then periodically top off with distilled water. Always wear gloves whenusing a concentrated sulfuric acid solutionin your at home or in workplace, because it can causesevere acidic chemical burnsand even secondary thermal burns due to dehydration when they come into contact with skin and body tissues. Useconcentrated sulfuric acid (95-98%)andsulfuric acid 93% (92-94%)carefully because these concentrations react with water, sodium hydroxide, alcohol,sugar, aluminum, bases, metals and calcium carbonate. If there is some leftover, trying to store it is way more challenging than disposing of it. If you are unsure, pour just a little in the container and see if there is any reaction before emptying the whole battery. 1. By neutralization, the acidic and basic property of both the acid and the base are destroyed. One of the recommended methods to neutralize sulfuric acid concentrations that are weak involves adding small amounts of sodium bicarbonate, more commonly known as baking soda, to the liquid and observing the results. Calcium carbonate will react with sulfuric acid to form calcium sulfate (also called gypsum) and carbon dioxide. Safety Tips to Remember When Disposing of Nitric Acid.

You should always handle such corrosive acids with the proper protective equipment. These studies are limited by co-exposure to several other workplace chemicals and/or tobacco smoke; however, the large number of studies reporting tumors suggests that sulfuric acid is a carcinogen. For example, neutralizing a 10% solution of HNO 3 acid will yield a temperature rise of nearly 20 0 C while neutralizing a 70% solution of concentrated Nitric acid will yield a temperature rise of over 120 0 C. This is enough to meltdown any thermoplastic piping system and hot enough to cause steam explosions. It's very important to always add the chemical to the water and not the water to the chemical. When equal amounts are mixed, the result is a neutral substance, salt water. If the personal protective equipment does not fit properly, it can make the difference between being safely covered or dangerously exposed.
