Water contains hydrogen bonding that cause a permanent polarity of the molecule. When a solid or other liquid is added to water the molecules of water orientate themselves so that the polar ends are breaking apart the bonds that are currently in the added compound. This is also known as Ionization of a solid into an aqueous solution.

Why does reducing solute particle size increase the speed at which the solute dissolves in water?
It exposes more of the solute surface to the water molecules.
What is a solute and solevent in a saltwater solution?
In a basic saltwater solution, the water molecules would be the solvent and the salt molecules would be the solute.
What is in between a solution and a suspention?
A solution is where the particles of a solute are dispersed evenly throughout the solvent while in a suspension, the particles of the solute are not dispersed evenly eg. Sand and water
Why oil molecules are not attracted to water molecules in vinegar?
because the vinegar particles are not attracted to the particles of oil.
What is the process in which a substance breaks up into smaller particles as it dissolves?
You question makes no sense. If particles dissolve they go into solution, they do not "break apart and scatter".
Why does reducing solute particles size increase the speed at which the solute dissolves in water?
It exposes more of the solute surface to the water molecules.
Why does increasing solute particles size increase the speed at which the solute dissolves in water?
It exposes more of the solute surface to the water molecules.
What must happen with the water molecules so that they can dissolve compounds?
The water molecules surround the solute (stuff being dissolved) and separate the particles.
Compare the solubility of olive oil and acetic acid in water?
well the solubility of any substance depnds on the forces acting between water molecules and solute particles compared to the forces acting between the solute particles
What happens when a solute dissolves in a liquid?
The particles of that solute go into the empty spaces around the water particles.
Is Sucrose soluble in water because the attractive forces between the solute particles are greater than the attractive forces between the solute and the solvent particles?
You've got it in reverse. When sucrose dissolves in water, sucrose is the solute, and water is the solvent. In order to dissolve, sucrose molecules have to be more attracted to water molecules than they are to other sucrose molecules. If the attraction of sucrose to sucrose was greater than the attraction of sucrose to water, then there would be no reason for the solid sucrose to turn into the aqueous sucrose solution. Sucrose molecules would simply remain firmly attached to each other if that were the case.

Does an egg get bigger in vinegar?
The egg was larger after remaining in water. Water has a lower concentration of solute molecules than the vinegar. Therefore, more water diffused to an area of higher concentration of solute particles.
Why does reducing solute particle size increase the speed at which the solute dissolves water?
As the particle size gets smaller, the surface area increases, and as the surface area increases, the ease with which water can hydrate the particles increases. When it is easier for water to hydrate the molecules, this increases the speed at which the solute dissolves.
How do solution formed?
Solutions form when the solute particles dissolve into the solvent particles. Then the solute particles go in between the solvent's particles and the solute's particles to therefore make a solution. The polarity of the water molecules (slightly negative around the oxygen atom, slightly positive on the hydrogen side) helps dissociate the weak bonds of the solute. The ions formed then flit about in the water, unable to reconnect with their original counterparts for any significant time (not enough to form a solid and drop out, called a precipitate). A solution is a substance dissolved in water or other solvents.
What does reducing solute particle size increase the speed at which the solute dissolves in water?
It exposes more of the solute to the water molecules
Does the salt move into or out of the cell?
Osmosis is the diffusion of water across a selectively permeable membrane (see "Diffusion" above). It occurs when a solute (example: salt, sugar, protein, etc.) cannot pass through a membrane but the water can pass through. In solutions where the solute concentration is high, the concentration of water molecules is low because some of the water molecules are attached to the solute particles and thus do not contribute to diffusion. In solutions where the solute concentration is low, the concentration of unbound water molecules is high. Water moves from areas where the concentration of unbound water molecules is high (low solute concentration) to areas where the concentration of unbound water molecules is low (high solute concentration). In general, water moves toward the area with a higher solute concentration because it has a lower water concentration
