Is sulfuric acid a strong acid or base?
Sulfuric acid is also called the “king of chemicals or acid” because of its strong acid and more reactive nature. The presence of more H + ions in the solution defines sulfuric acid as a good conductor of electricity and a strong electrolyte.
Is sulfuric acid an ionic or molecular bond?
Sulfuric acid is a strong acid, so the two ions are dissociated in water. Sulfuric acid is a covalen or molecular compound. Four oxygens are bound to the central sulfur atom, two of them by double bonds and two of them by single bonds. The oxygens with single S~O bonds are, in turn, bound covalently to a hydrogen each.
Is sulfuric acid solid liquid or gas?
Like all matter, sulfuric acid can exist as a solid, liquid, or gas. The temperature of the acid determines which state of matter it is in, with lower temperatures slowing the atoms down until they become solid and higher temperatures creating enough movement in the atoms that it becomes first a liquid and then a gas.
Can you mix sulfuric acid and phosphoric acid?
The most important connection between sulfuric acid and phosphoric acid is usually that one is required to make the other: phosphoric acid is created when sulfuric acid interacts with tricalcium phosphate, a chemical compound widely present in the soil.

Is sulfuric acid a mixture?
Is Sulfuric Acid Compound or Mixture? Sulfuric acid (H2SO4) is a compound of hydrogen, sulfur, and oxygen that combine chemically. It's not a mixture because the ratio of composition is fixed.
Is sulfuric acid a homogeneous mixture?
In diluted sulfuric acid, water and sulfuric acid are mixed uniformly and thoroughly. Therefore, it is a homogeneous mixture, whereas pure sulfuric acid is a compound.
Is sulfur dioxide an element or compound?
Sulfur dioxideSulfur dioxide / IUPAC IDsulfur dioxide, (SO2), inorganic compound, a heavy, colourless, poisonous gas. It is produced in huge quantities in intermediate steps of sulfuric acid manufacture.
Is he a compound or element?
helium (He), chemical element, inert gas of Group 18 (noble gases) of the periodic table. The second lightest element (only hydrogen is lighter), helium is a colourless, odourless, and tasteless gas that becomes liquid at −268.9 °C (−452 °F).
What is the grade of sulfuric acid?
Grades of sulfuric acid. Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO. 3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade is more stable in storage, and is the usual form of what is described as "concentrated sulfuric acid".
How is sulfur dioxide oxidized?
The sulfur dioxide is oxidized to sulfur trioxide by oxygen in the presence of a vanadium (V) oxide catalyst. This reaction is reversible and the formation of the sulfur trioxide is exothermic. 7 ), also known as fuming sulfuric acid. The oleum is then diluted with water to form concentrated sulfuric acid.
What is the concentration of sulfuric acid?
Although nearly 100% sulfuric acid solutions can be made, the subsequent loss of SO#N#3 at the boiling point brings the concentration to 98.3% acid. The 98.3% grade is more stable in storage, and is the usual form of what is described as "concentrated sulfuric acid". Other concentrations are used for different purposes. Some common concentrations are:
How does sulfuric acid decompose?
Drops of concentrated sulfuric acid rapid ly decompose a piece of cotton towel by dehydration. Play media. An experiment that demonstrates the dehydration properties of concentrated sulfuric acid. When concentrated sulfuric acid comes into contact with sucrose, slow carbonification of the sucrose takes place.
What is sulfuric acid used for?
Sulfuric acid is also a key substance in the chemical industry. It is most commonly used in fertilizer manufacture, but is also important in mineral processing, oil refining, wastewater processing, and chemical synthesis.
Why does acid not boil?
Acid will not boil, because of its higher boiling point. Warm water near the interface rises due to convection, which cools the interface, and prevents boiling of either acid or water. In contrast, addition of water to concentrated sulfuric acid results in a thin layer of water on top of the acid.
How much sulfuric acid is in 10M?
In particular, "10M" sulfuric acid (the modern equivalent of chamber acid, used in many titrations ), is prepared by slowly adding 98% sulfuric acid to an equal volume of water, with good stirring: the temperature of the mixture can rise to 80 °C (176 °F) or higher. Sulfuric acid reacts with its anhydride, SO.
Overview
Sulfuric acid (American spelling and the preferred IUPAC name) or sulphuric acid (Commonwealth spelling), known in antiquity as oil of vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with the molecular formula H2SO4. It is a colorless, odorless and viscous liquid that is miscible with water.
Pure sulfuric acid does not exist naturally on Earth due to its strong affinity to water vapor; for this reason, it is hygroscopic and readily absorbs water vapor from the air. Concentrated sulfuric acid is highly corrosive towards o…

Chemical properties
Because the hydration reaction of sulfuric acid is highly exothermic, dilution should always be performed by adding the acid to the water rather than the water to the acid. Because the reaction is in an equilibrium that favors the rapid protonation of water, addition of acid to the water ensures that the acid is the limiting reagent. This reaction is best thought of as the formation of hydronium ions:
Occurrence
Pure sulfuric acid is not encountered naturally on Earth in anhydrous form, due to its great affinity for water. Dilute sulfuric acid is a constituent of acid rain, which is formed by atmospheric oxidation of sulfur dioxide in the presence of water – i.e. oxidation of sulfurous acid. When sulfur-containing fuels such as coal or oil are burned, sulfur dioxide is the main byproduct (besides the chief products carbon oxides and water).
Manufacture
Sulfuric acid is produced from sulfur, oxygen and water via the conventional contact process (DCDA) or the wet sulfuric acid process (WSA).
In the first step, sulfur is burned to produce sulfur dioxide.
S(s) + O2 → SO2
The sulfur dioxide is oxidized to sulfur trioxide by oxygen in the presence of a vanadium(V) oxide catalyst. This re…
Uses
Sulfuric acid is a very important commodity chemical, and indeed, a nation's sulfuric acid production is a good indicator of its industrial strength. World production in the year 2004 was about 180 million tonnes, with the following geographic distribution: Asia 35%, North America (including Mexico) 24%, Africa 11%, Western Europe 10%, Eastern Europe and Russia 10%, Australia and Oceania 7%, South America 7%. Most of this amount (≈60%) is consumed for fert…
History
The study of vitriol, a category of glassy minerals from which the acid can be derived, began in ancient times. Sumerians had a list of types of vitriol that they classified according to the substances' color. Some of the earliest discussions on the origin and properties of vitriol is in the works of the Greek physician Dioscorides (first century AD) and the Roman naturalist Pliny the Elder (23–79 AD). Galen also discussed its medical use. Metallurgical uses for vitriolic substanc…
Safety
Sulfuric acid is capable of causing very severe burns, especially when it is at high concentrations. In common with other corrosive acids and alkali, it readily decomposes proteins and lipids through amide and ester hydrolysis upon contact with living tissues, such as skin and flesh. In addition, it exhibits a strong dehydrating property on carbohydrates, liberating extra heat and causing secondary thermal burns. Accordingly, it rapidly attacks the cornea and can induce permanent b…
