Top 10 acids factsChemistry 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.
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.
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.
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.
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).
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.
Hydrofluoric acid is a very strong, reactive and corrosive acid. Which material is resistant?
Plastic. Hydrofluoric acid is a precursor to almost all fluorine compounds, including: fluoxetine (Prozac), PTFE (Teflon).It is a colourless solution that is highly corrosive, capable of dissolving many materials, especially oxides. Because of its high reactivity toward glass and moderate reactivity toward many metals, hydrofluoric acid is usually stored in plastic containers.
Which of these compounds is acid?
HCOOH. It is a formic acid formula.
