Sulphuric acid is high boiling and viscous liquid this is due to the association of molecules together through hydrogen bonding.

Why is sulphuric acid syrupy viscous?
Because it is made up of minerals,it’s a mineral acid… And it ionises completely when dissolved in water and gives a higher concentration of aq. H+ ions…. That’s why it’s oily and viscous..
Why sulphuric acid is oily and viscous liquid?
The crystals of green vitriol (FeSO₄. 7H₂O) are heated and distilled to give sulfuric acid which is in the form an oily viscous liquid. The molecules of H₂SO₄ are larger than that of H₂O since the Vander Waal’s forces are higher in H₂SO₄.Therefore, it is a more viscous fluid than water.
Why sulphuric acid is volatile?
Sulphuric acid has high boiling points and this is why it is used in the preparation of volatile acids such as Hydrochloric acid i.e. HCl, HNO3 and acetic acid from their salts.
Why is sulphuric acid more viscous than water?
Solution: Sulphuric acid is more viscous than water because its molecules form hydrogen bonds among themselves. This restricts the movement of the molecules in the liquid, making it highly viscous.sulphuric acid is capable of forming hydrogen bonds with water molecules.
Why is pure acid highly viscous?
The given phosphoric acid H3PO4 is highly viscous and high boiling point due to the presence of hydrogen bonding in concentrated solution hence the answer is Option (4) “it has PO.Regards.
How is Sulphuric acid manufactured by contact process?
contact process, modern industrial method of producing sulfuric acid; it has largely replaced the chamber, or lead-chamber, process. Sulfur dioxide and oxygen, passed over a hot catalyst, unite to form sulfur trioxide, which in turn combines with water to make sulfuric acid.
Why sulphuric acid has high boiling point and viscosity?
Answer: Presence of H-bond in H2SO4 produces greater attraction among the molecules and H2SO4 molecules form long chains by H-bonding. Due to greater forces of attraction H2SO4 is viscous and has high boiling point.
Is sulfuric acid oily?
Sulfuric acid is a strong mineral acid with the chemical formula H2SO4. It is a colorless, oily liquid. The pure acid has a density of 1.834 at 25°C and freezes at 10.5°C (50.90°F).Sulfuric acid (also known as vitriol or oil of vitriol) is a highly corrosive, dense, oily liquid.
Is H2SO4 a dehydrating agent?
As well as being a strong acid, sulfuric acid is also a dehydrating agent, meaning it is very good at removing water from other substances.
Why is sulphuric acid a reducing agent?
In H2SO4 sulphur is in +6 oxidation state. To act a a reducing agent one should lose electrons i.e; the atom should go from lower positive oxidation state to higher positive oxidation state. As sulphur is already in it’s maximum possible oxidation state in H2SO4, further loss of electrons is not possible.
Which is more volatile hi or H2SO4?
Reason: HI is more volatile than H2SO4 29.
Is H2SO4 highly volatile?
(i) Concentrated sulphuric acid is a non-volatile acid.
Why sulphuric acid and glycerol has higher viscosity than water?
Correct explanation : Sulphuric acid is more viscous because of the presence of greater extent of hydrogen bonding in the molecules.
Which is more viscous H2SO4 or HNO3?
Compared to other acids like HCl and HNO3, H2SO4 is highly syrupy and viscous in nature.
How is liquid viscosity measured?
The viscosity of a liquid (see Viscosity) is measured using a viscometer, and the best viscometers are those which are able to create and control simple flow fields.Most modern viscometers are computer- or microprocessor-controlled and perform automatic calculations based on the particular geometry being used.
Why phosphoric acid is viscous?
Pure phosphoric acid is very viscous because it has groups which are bonded by many hydrogen bonds.
Why phosphoric acid is syrupy and viscous?
Phosphoric acid is syrupy in nature due to hydrogen bonding.
Is H2SO4 a Sulphonating agent?
– We know that sulphuric acid can form sulfonate ions in its solution. These sulfonate ions can act as an electrophile for aromatic electrophilic substitution reaction. Thus, we can say that concentrated ${H_2}S{O_4}$ is a good sulfonating agent.
How is sulphuric acid prepared by lead chamber process give its principle?
chamber process, also called Lead-chamber Process, method of producing sulfuric acid by oxidizing sulfur dioxide with moist air, using gaseous nitrogen oxides as catalysts, the reaction taking place primarily in a series of large, boxlike chambers of sheet lead.
