Is it breaking of intermolecular forces or breaking of intramolecular forces?
djh101 said:Intermolecular. When you dissolve table salt, the bonds between the sodium and chloride are being broken and the ions dispersed throughout the liquid.

Intermolecular is between different molecules.Intramolecular is within a single molecule.
abi.ayan said:Though the attraction between the ions in ionic bond is stronger than the intermolecular forces between the molecules ,ionic compounds dissolve in water but not covalent compounds?can anyone explain??
Borek said:I would not classify forces between sodium and chloride in NaCl as intermolecular.
Intermolecular forces are forces of attraction or repulsion which act between neighboring particles (atoms, molecules or ions).

djh101 said:Water is polar, so its poles are attracted to the charged ions. If you try to dissolve a nonpolar compound in water, the attraction is weak and entropy favors maximizing water bonding to itself.
Dissolving refers to the process of a solid substance, known as the solute, being mixed with a liquid substance, known as the solvent, and forming a homogeneous mixture. This results in the solute particles being dispersed evenly throughout the solvent, creating a solution.
The rate of dissolving can be affected by several factors, including temperature, surface area, and agitation. Higher temperatures can increase the kinetic energy of the particles, leading to faster dissolving. A larger surface area of the solute can also increase the rate of dissolving, as it allows for more contact between the solute and solvent. Agitation, such as stirring, can also speed up the dissolving process by helping to disperse the solute particles evenly.
Dissolving, melting, and evaporation are all physical processes that involve changes in the state of matter. However, dissolving specifically refers to the mixing of a solute and solvent, while melting is the process of a solid changing into a liquid, and evaporation is the process of a liquid changing into a gas. Dissolving does not involve a change in the chemical composition of the substances, while melting and evaporation do.
No, not all substances can dissolve in all liquids. The solubility of a substance, or its ability to dissolve, depends on its polarity and the polarity of the solvent. Polar substances, which have uneven distribution of electrons, are more likely to dissolve in polar solvents, while nonpolar substances, which have an even distribution of electrons, are more likely to dissolve in nonpolar solvents. Additionally, the strength of the intermolecular forces between the solute and solvent also plays a role in solubility.
You can determine if a substance is dissolved in a solution by observing whether the mixture is homogeneous or heterogeneous. If the mixture is uniform in appearance and the solute particles are not visible, it is likely that the substance has dissolved in the solution. Conversely, if the mixture appears to have separate layers or the solute particles are still visible, the substance may not have fully dissolved.
