Why is concentrated phosphoric acid syrupy in nature?
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.
Why is phosphoric acid viscous?
Viscosity increases with the increase in the strength of intermolecular forces. Phosphoric acid (H3PO4) possess intermolecular H− bonding. Thus it is viscous.
What is the nature of phosphoric acid?
Physical Properties: Pure phosphoric acid is a white crystal-like solid with a melting point of 42.35° C. When it is less dense, it is a colorless, viscous liquid, odorless with a density of 1.885 g/mL. It is non-toxic and non-volatile in nature. The most commonly used phosphoric acid concentration is 85\% in H2O water.
Why is Sulphuric acid syrupy?
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..
What does phosphoric acid smell like?
Phosphoric acid
| Names | |

Why is pure phosphoric acid a viscous liquid?
Pure phosphoric acid is very viscous because it has groups which are bonded by many hydrogen bonds.

Where is phosphoric acid in nature?
Phosphoric acid is made from the mineral phosphorus, which is found naturally in the body. It works with calcium to form strong bones and teeth. It also helps support kidney function and the way your body uses and stores energy.
Why is phosphoric acid called orthophosphoric acid?
Although phosphoric acid does not meet the strict definition of a strong acid, the 85\% solution can still severely irritate the skin and damage the eyes. The name “orthophosphoric acid” can be used to distinguish this specific acid from other “phosphoric acids”, such as pyrophosphoric acid.
Why is Sulphuric acid viscous in nature?
Sulphuric acid is highly viscous in nature because its molecules are associated with hydrogen bonding. It is a highly corrosive chemical.
Why H2SO4 is oily and viscous?
Sulfuric acid (H 2SO 4) is capable of forming hydrogen bonds, both with water and other H 2SO 4 molecules. These bonds between molecules decrease overall molecular movement, thereby increasing the viscosity of the solution.
Can phosphoric acid hurt you?
As a corrosive chemical, phosphoric acid can irritate and burn the eyes and skin. It can also irritate the nose, throat and lungs, leading to wheezing and coughing.
