Acids questionsThis is a list of recently added questions about acids.
Hydrofluoric acid is a very strong, reactive and corrosive acid. Which material is resistant?
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.
What is H₂SO₂ ?
Nitric acid (III)
Sulfoxylic acid (H2SO2) (also known as hyposulfurous acid or sulfur dihydroxide)) is an unstable oxoacid of sulfur in an intermediate oxidation state between hydrogen sulfide and dithionous acid. It consists of two hydroxy groups attached to a sulfur atom.
Which acid belongs to the carboxylic acids?
Acetic acid (CH3COOH) has a carboxylic group (COOH). Carbonic acid (H2CO3), nitric acid (HNO3) and hydrochloric acid (HCL) of this group do not.
Which acid mostly contributes to acid rains?
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 the main industrial use of sulfuric acid and nitric acid?
synthesis of plastics
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.
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 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.
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.
