Acid Property #1: The word acid comes from the Latin word acere‚ which means "sour." All acids taste sour. Well known from ancient times were vinegar‚ sour milk and lemon juice. Aspirin (scientific name: acetylsalicylic acid) tastes sour if you don’t swallow it fast enough. Other languages derive their word for acid from the meaning of sour. So‚ in France‚ we have acide. In Germany‚ we have säure from saure and in Russia‚ kislota from kisly. Base Property #1: The word "base" has a more complex

Inference Abstract of the work under taken Antacids are medicines that neutralize stomach acid. They are used to relieve acid indigestion‚ upset stomach‚ sour stomach‚ and heartburn. Antacids are taken by mouth and work by neutralizing excess stomach acid. They contain ingredients such as aluminum hydroxide‚ calcium carbonate‚ magnesium hydroxide

STANDARDIATION OF ACID AND BASE Eunice Ivy B. Gamboa ABSTRACT Solutions of known concentration are prepared by dissolving measured masses of standard acids in distilled water. The concentrations of unknown solutions of sodium hydroxide are determined by titration. An acid solution reacts with a base solution in a "neutralization" reaction. Titrations permit the concentrations of unknown acids/bases to be determined with a high degree of accuracy. In order to analyze unknown acids/bases‚ we must have

Acid rain is a rain or any other form of precipitation that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants‚ aquatic animals and infrastructure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide‚ which react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into the atmosphere with positive results. Nitrogen

Vol. 1 ACETIC ACID 115 ACETIC ACID 1. Introduction Acetic acid [64-19-7]‚ CH3COOH‚ is a corrosive organic acid having a sharp odor‚ burning taste‚ and pernicious blistering properties. It is found in ocean water‚ oilfield brines‚ rain‚ and at trace concentrations in many plant and animal liquids. It is central to all biological energy pathways. Fermentation of fruit and vegetable juices yields 2–12% acetic acid solutions‚ usually called vinegar (qv). Any sugar-containing sap or juice can

Determination of Unknown Acid KEYWORDS: quantitative analysis‚ titration‚ buret‚ endpoint‚ standardization‚ half-equivalence point‚ calorimetric titration‚ potentiometric titration ABSTRACT: The concentration of sodium hydroxide was determined by colorimetric titration‚ and the identity of an unknown acid was determined by potentiometric titration. In the first titration‚ a strong acid standard‚ potassium hydrogen phthalate (KHP)‚ was used‚ to determine the concentration of a strong base‚ sodium
