acids facts Selected as the most interesting among chemistry related questions in Chemistry quiz What is the effect of nicotinic acid on human organism?It is essential for functioning. Nicotinic acid, better known as niacin or vitamin B3, has nothing in common with tobacco. Chronic lack of niacin leads to pellagra, a vitamin deficiency disease.Created by: globalquiz.orgtobacco facts » What is the strongest known acid?Fluoroantimonic acid is an ionic liquid created by reacting hydrogen fluoride with antimony pentafluoride in stoichiometrically equivalent amounts. The 1:1 combination forms the strongest known superacid, 10^16 (10 quadrillion) times stronger than 100% sulfuric acid.Created by: globalquiz.orgchemistry facts » Which acid causes the sourness of green apples?Malic acid is more sour than citric acid, and is the source of extreme tartness in so-called extreme candy. Malic acid occurs naturally in all fruits and many vegetables.Created by: Kasiafruits facts » Which acid is used for the production of explosives?Nitric acid is the primary reagent used for nitration - the addition of a nitro group. Nitration reactions are notably used for the production of explosives, for example synthesis of nitroglycerine, the conversion of guanidine to nitroguanidine and the conversion of toluene to trinitrotoluene (TNT).Created by: globalquiz.orgtechnology facts » What is the main industrial use of sulfuric acid and nitric acid?Fertilizers production. World production of sulfuric acid in 2004 was about 180 million tonnes. About 60% of this amount is consumed for fertilizers, particularly superphosphates, ammonium phosphate and ammonium sulfates. Similarily, 75–80% of the 26M tons of nitric acid produced annually is used to produce ammonium nitrate fertilizer.Created by: Monica Stillerchemistry facts » Which acid mostly contributes to acid rains?Sulfuric acid. The most important gas which leads to acidification is sulfur dioxide, coming from fossil fuel combustion and industry (and, in lesser amounts, from volcanoes and wildfires). In recent years, emissions of nitrogen oxides which are oxidized to form nitric acid are of increasing importance due to stricter controls on emissions of sulfur containing compounds. Created by: Cleoecology facts » What is the common name for acetylsalicylic acid?Aspirin has an antiplatelet effect. Low doses of aspirin may be given immediately after a heart attack to reduce the risk of another heart attack or of the death of cardiac tissue.Created by: globalquiz.orgmedicine facts » What is exactly the pH value of distilled water?It depends on the temperature. Pure water is about 7 at 25 °C; this value decreases with increasing temperatures. At 50 °C, it is 6.55. It is also worth to note, that water that has been exposed to air is mildly acidic, because it absorbs carbon dioxide from the air.Created by: globalquiz.orgwater facts » Play chemistry quiz and see all the questions.
