![]() ![]() When a water solution of acid is mixed with a water solution of base, a saltand water are formed this process, called neutralisation, is complete only if the resultingsolution has neither acidic nor basic properties. Bases in watersolutions exhibit these common properties: they taste bitter turn litmus paper blue andfeel slippery. Acids in watersolutions exhibit the following common properties: they taste sour turn litmus paperred and react with certain metals, such as zinc, to yield hydrogen gas. ![]() It ismeasured by titration with a standard solution of base to a specified end point.Īcids & Bases are two related classes of chemicals the members of each class have anumber of common properties when dissolved in a solvent, usually water. These are violently explosive compounds.Īcid Any substance capable of giving up a proton a substance that ionizes in solution togive the positive ion of the solvent a solution with a pH measurement less than 7.Īcidity the quantitative capacity of aqueous solutions to react with hydroxyl ions. Produced by the action of wateron calcium carbideand catalytically from naphtha.Īcetylide A carbide formed by bubbling acetylene through a metallic salt solution, egcuprous acetylide, Cu2C2. The oxyacetylene torch mixes and burns oxygenand acetylene to produce a very hot flame-as high as 3480ÝC (6300ÝF)-that can cutsteel and weld iron and other metals. It is used to makeneoprene rubber, plastics, and resins. Explosiveon contact with air, it is stored dissolved under pressure in Acetone. Boiling Point 56ÝC.Useful solvent for acetylene, also known as the simplest saturated ketone.Īcetylene or ethyne, a colourless gas and the simplest alkyne Hydrocarbon. It is used in making synthetic Resins andfillers, smokeless powders, and many other organic compounds. Acetone is widely used in industryas a solvent for many organic substances. Used as an intermediate for various explosives, and a solvent forvarious dyes.Īcetone colourless, flammable liquid. Thesampling plans so identified have a high probability of accepting lots containing materialwith a process average not greater than the designed value of the AQL.Īcetin also known as glyceryl monoacetate, a colourlesshydroscopic liquid. Generally accepted as-273.15ÝCĪcceptance Quality Level (AQL) A nominal value expressed in terms of percentagedefective per hundred units, by which a group of sampling plans is identified. Abelite An explosive, composed mainly of ammonium nitrate and trinitrotoluene.Ībsolute Zero The least possible temperature for all substances.
