Which chemical can neutralise sulfuric acid spill?

Acid Spills (hydrochloric or sulfuric acid):. 1. Neutralize spill with sodium bicarbonate/baking soda. 2. Wait until bubbling/fizzing has stopped. 3. When using a neutralizing spill kit, the kits are buffered and will not have a bubbling action. Be careful not to over-neutralize. 4. read more

Barium nitrate will not neutralize but will convert your spill to a mixture of insoluble barium sulfate and corrosive nitric acid as well as the sulfuric. Sulfuric acid does not really give fumes ( though mists are nasty) but HNO3 can, especially if it comes in contact with other reactive materials (e.g. aluminum equipment). read more

3. When using a neutralizing spill kit, the kits are buffered and will not have a bubbling action. Be careful not to over-neutralize 4. Test pH of the spill after the neutralization reaction has stopped with pH paper 5. Once pH is between 6 and 9, the material can be transferred into an appropriate secondary container for disposal 6. read more
