Why sodium chloride is soluble in water but benzene is insoluble?

Sodium chloride is an ionic solid and water is a polar solvent. Water molecules attract Na+andCl- ions by their negative and positive poles respectively. on the other hand, benzene and hexane are non-polar organic solvents and they cannot solvate Na+andCl- ions. hence, sodium chloride is insoluble in benzene or hexane.

Why will NaCl not dissolve in benzene?

The attraction between the solute (NaCl) and solvent (water) is so great that it is strong enough to pull the ions from their positions in the crystal. This is because benzene is a non polar solvent and hence benzene molecules cannot attract the solute (NaCl) molecules and NaCl does not dissolve in Benzene.

Why does sodium chloride is soluble in water?

When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules. Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together.

What is sodium chloride not soluble in?

NaCl is not very soluble in ethanol, but it does dissolve to the extent of 0.65 g of NaCl per kilogram of ethanol. The strongest forces in NaCl are the ion-ion attractions between Na+ and Cl- ions.

Why is NaCl soluble in water but not hexane?

In contrast, water, a clear, colorless liquid at room temperature, is polar and interacts with other water molecules through H-bonds. NaCl is a salt held together by ionic bonds. In a sense it is as polar a substance as you can get. It dissolves in water (as you know from experience) but not in hexane.

Why is sodium carbonate more soluble in water than benzene?

most of ionic compound are polar in nature and when it added to the water they broke down in ions, polarity of the water molecules attracts this ions and so it is soluble in water. benzen is non polar organic compound, boken down ions are not attracts to benzen, so it is insoluble in it.

When sodium chloride dissolves in water the solution contains?

Explanation: While it’s true that when a crystal of the ionic substance sodium chloride is dissolved in water the sodium and chloride ions separate from one another, they do not separate to form lumps of sodium metal or to form chlorine gas. Rather, they remain as single Na+ and Cl− ions, surrounded by water molecules.

When sodium chloride dissolves in water the sodium ions?

Hence, we can conclude that when NaCl is dissolved in water, the sodium ion becomes hydrated. Hence, the correct option for this question is D that is hydrated. Note: The salt in a chemistry can be described by having an ionic form get-together with the cations and the anions.

Is sodium chloride a polar or nonpolar solvent?

Sodium Chloride (NaCl) which is an ionic compound acts as a polar molecule. Usually, the large difference in electronegativities in sodium and chlorine makes their bond polar.

Why is sodium chloride insoluble in acetone?

When the lattice energy is larger than the energy released by solvation of the ions, namely that of Na+ by complexation with acetone, the compound becomes insoluble and precipitates from the solution (source).

Is NaCl soluble in benzene?

Sodium chloride is soluble in water but not in benzene because.

Why is sodium chloride soluble in benzene but insoluble in water?

As sodium chloride is polar in nature and benzene is non polar molecule therefore it is insoluble in benzene but as water is a polar solvent and therefore sodium chloride is soluble in water but insoluble in benzene. To break the NaCl lattice it takes energy. In water the ion of NaCl are hydrated, i.e. forming bonds with e few water molecules.

Why is NaCl soluble in water?

Why is NaCl Soluble in Water Strong sodium ions bound to negative chloride ions are made of salt (sodium chloride). Water can dissolve salt because the negative chloride ions are attracted by the positive portion of water molecules and the positive sodium ions are attracted by the negative portion of water molecules.

Is sodium chloride soluble in ionic or nonpolar solvents?

Sodium chloride is an ionic compound and like other ionic compounds it is soluble in ionic or polar solvents and not in organic solvents which are non-polar. Non-polar compounds like organic compounds are soluble in non-polar solvents and not in ionic or polar solvents. Thus we can say, like dissolves like is the rule. Hope this helps .:)

What is the solubility of KCl in benzene?

KCl is an ionic compound and can dissolve only in polar solvents like water. This can be generalized by the solubility principle ‘like dissolves like’. KCl is insoluble in benzene because benzene is a nonpolar solvent. Firstly, it’s spelt benzene in English.
