Salt and sugar are soluble in water but sand is Not | Solutions | Chemistry

This simple demonstration uses three beakers of water to let you compare the results of mixing sand, sugar, and salt in water. After adequate stirring, the salt and sugar are not visible as both of them have completely dissolved in water. These are called soluble substances. Sand is still visible and retains its form even in water, it is an insoluble substance.

Sir thank you very much, as I am able to complete my school project now.☺️☺️

For people that ask why salt and sugar is soluble in water but sand isnt, here is the explanation. (Correct me if im wrong)

C6H12O6 (glucose) and NaCl (salt) dissolves in water because they have a net dipole moment as compared to SiO2 (sand) crystals

SiO2 has a tetrahedral structure within its giant covalent structure that cancels out any little dipole moments. Hence the δ- at oxygen and δ+ at hydrogen of the polar H2O molecule cannot effectively bond with the SiO2.
However, NaCl crystals are a ionic lattice of alternating Na+ positive cations and Cl- negative anions which react readily exothermically with the H2O polar δ+ δ- dipoles, slowly taking apart the lattice as Na+ and Cl- are hydrated and dissolved in H2O by molecules surrounding them.

Glucose on the other hand, have highly electronegative O atoms which draws electrons from bonded H atoms, creating highly electron deficient H atoms with δ+. This forms a hydrogen bond with water molecules.


EDIT:
Also, table sugar is a lot more soluble than salt because while ion dipole interactions between water molecules and Na+ and Cl- are stronger than hydrogen bonds, glucose has 5 hydroxyl sites to form H bonds with water molecules, which boosts solubility. However, the main reason is that glucose molecules are more massive per molecule, hence more mass of glucose cam be dissolved.

Vaisy app acha samgaty hai thank you ☺️💕 sir

I dissolved some pink salt in a glass of warm water and noticed some pink granules didn't dissolve. I guess they were sand particles which is very concerning since I would have sprinkled some salty sand on my salad!

Thank goodness for you and your mother is a lot to do in the day but I will not be able to make it to the meeting tonight but I will be there at the same time I don't have a car so I can get a ride to the airport on

it sounded like he said "turd glass" 0:39

[abdurahimanvardh]

Which property of sugar makes it different from white crystalline sand?

[rajeshshahi]

Is that pure SiO2 it doesn't look like that it could be a mixture of pureSiO2 and CaCO3

who else is here because of homework or a project

Sir what will be the aim of this experiment for std 4th plzz reply nowbits urgent

[PakistanFan_person]

Hi really like the video thx so much, from Argentina ¯⁠\⁠_⁠ಠ⁠_⁠ಠ⁠_⁠/⁠¯

[genocidevirus]

Damn. I always wondered why there was so much sand at the beach.

[Animemaster]

Why can't we see salt or sugar particles after dissolving it in water

[quizguru]

We totally certain, we made questions around the present video.

this vid was uploaded 7 years ago do u guys think he will reply

[nikhilkhanal]

why sugar and salt are soluble but sand is not ?
i know sand are not soluble and salt and sugar are soluble but why?

[makethestar]

Sir But why doesn't salt dissolve in I am waiting for your answer.

[northpandawest]

idk wht salobe is cuz im doing a project lol
