When a salt crystal is dropped into water, the water surrounds the sodium and chloride ions with oppositely charged poles of the water molecules. Thus insulated from the attractiveness of other molecules of salt, the ions disperse, and the whole crystal gradually dissolves.

Water striders benefit from surface tension. When salt is placed in water the atoms of the salt start to separate from each other making the molecule rip apart because salt has a negative and a positive side making it polar and water also is polar and polar molecules attract to other polar molecules.

If sodium chloride is dissolve in water (H2O), the water molecules will dissociate the ions present in sodium chloride. Ionic compound like Nacl dissolves in water to form an electrolytes.

Explanation: Like dissolves like. Water is a polar molecule therefore, it will dissolve polar solutes such as, ionic compounds and polar molecular compounds. That is why, vitamin A is not soluble in water, However, vitamin C is soluble.

Each Granulated sugar is touched with water so exposed surface is highest from others so its solubility is highest. Was this answer helpful?

Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster.

1) We can make the solute dissolve faster by heating the mixture. 2) We can make the solute dissolve faster by stirring the mixture. 3) We can make the solute dissolve faster by grinding the solute before it is put into the solvent.

Monolayer: When soap is added to water, the ionic-salt end of the molecule is attracted to water and dissolved in it. The non-polar hydrocarbon end of the soap molecule is repelled by water.

Iodine dissolves easily in chloroform and hexane but does not dissolve in water.
