Because of intermolecular hydrogen bonding sulphuric acid (H2SO4.) is syrupy simply because it is a viscous liquid.
Why is H2SO4 a syrupy liquid?
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 is sulphuric acid viscous?
Sulphuric acid is high boiling and viscous liquid this is due to the association of molecules together through hydrogen bonding. Sulphuric acid is a high boiling viscous liquid.
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 is phosphoric acid syrupy and viscous?
In liquids the interaction between molecules is when they bump or collide with each other and rub against each other.In phosphoric acid, the hydrogen bonding between the hydrogen atoms and the oxygen atoms create this effect and it is help by the relatively larger size of the molecule. Thus, phosphoric acid is syrupy.
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 conc H2SO4 is viscous and has high boiling point?
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.
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.
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.
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.
Why sulphuric acid is non volatile?
We know that one of the many properties of sulphuric acid is that it is a non- volatile acid. 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 h3po4 is syrupy liquid?
Due to extensive hydrogen bonding, it is a syrupy liquid.
What does phosphoric acid smell like?

How is sulphuric acid manufactured by contact process Why is sulphuric acid syrupy?
Sulphuric acid can be yielded by diluting sulphur trioxide in water. This is a very dangerous method and not followed. Adding sulphur trioxide to water is highly exothermic and causes the fuming of sulphuric acid. Further dissolution of sulphur trioxide in water is prevented by the fumes.
How is sulphuric acid prepared?
Sulfuric acid is prepared industrially by the reaction of water with sulfur trioxide (see sulfur oxide), which in turn is made by chemical combination of sulfur dioxide and oxygen either by the contact process or the chamber process.Sulfuric acid is commonly supplied at concentrations of 78, 93, or 98 percent.
How is sulphuric acid prepared from Oleum?
Oleum is produced in the contact process, where sulfur is oxidized to sulfur trioxide which is subsequently dissolved in concentrated sulfuric acid. Sulfuric acid itself is regenerated by dilution of part of the oleum.
What does sulfuric acid taste like?
It tastes sour not that you would taste it in a laboratory! It turns blue litmus red except when it is the covalent molecule, i.e. 100% H2SO4. Concentrated sulfuric acid is very hygroscopic.
Is Sulphuric acid corrosive?
Sulfuric acid (H2S04) is a corrosive substance, destructive to the skin, eyes, teeth, and lungs. Severe exposure can result in death.
Why does sulfuric acid turn brown?
Sulfuric acid is a oily liquid at room temperature. It is colorless, but often has a very light yellowcolor when slightly contaminated with iron ions. Even very small amounts of dissolved organic matter can change the color of concentrated sulfuric acid to paleyellow or pink, red, brown, and even black.
Why does sulfuric acid have low boiling point?
When sulfur dioxide is boiled, it is the weak intermolecular forces which are broken and not the strong covalent bonds. Only a small of amount of energy is required to break the intermolecular forces so the boling point is low.
