Cleaning up spilled acid requires disposing of the material in a plastic or glass container with a sealable lid; a chemical neutralizer should be used if the spilled acid is in liquid form. Safe clean-up requires the use of eye and skin protection, such as goggles, acid-resistant gloves, shoe covers and a lab coat. Ensure all sources of ignition are turned off before beginning the clean-up process.Know More
Limbs can suffer serious damage when exposed to spilled acid. If the material is dry, it can simply be collected in a container of plastic or glass for disposal.
For a liquid spill, apply a spill pillow, pad or other absorbent agent to keep the spill from spreading. Then, add the neutralizing agent to the acid spill. Weak bases, like calcium carbonate, sodium carbonate and sodium bicarbonate are ideal. The neutralizer should be added slowly from the edges inward to prevent splattering. After adding the neutralizing agent, mix with a spatula or similar tool.
To ensure the mixture is neutralized, a pH test should be conducted. According to the Environmental and Health Safety Department of the University of Iowa, a pH reading of 6 to 8 is no longer hazardous. At this point, the acid can be absorbed, sealed away, labeled and left for collection. The area of the spill should be ventilated and cleaned with detergent and water.Learn more about Acids & Bases
Pure boric acid is a powder commonly used as a disinfectant or insecticide. It is found in the pharmacy section of stores. It is a mild acid with the chemical formula H3BO3.Full Answer >
Hydrochloric acid is used in the rubber, photographic, textile and electroplating industries, and is used to manufacture dyes, chlorides and fertilizers. The chlorides produced from hydrochloric acid are used for the cleaning and pickling of metal items, as a solvent and catalyst in organic syntheses, to remove scale from boilers and to refine ore when producing tantalum and tin.Full Answer >
Because the pH of hydrochloric acid can vary depending on its concentration, specific indicators are used to determine when it reaches a certain pH during titration. Bromocresol green is used for this purpose because it exhibits a color change within the pH range of 3.8 to 5.4.Full Answer >
