Is it true that a solute with small particles dissolve more quickly than one with large particles?

In general, yes; the same amount of mass will probably dissolve more slowly if divided into a few large particles than into many small particles. This is because dissolution takes place at the surface, and small particles have a higher surface area to volume ratio than large particles (assuming the particles are the same shape).

∙ 14y agoYes, a soluble particulate substance (like a powder) will go into solution more quickly under the same conditions (temperature, pressure, and solution saturation, for example) if the particles are smaller. It is a matter of particle surface area and volume. Small particles have lots of surface area to offer to a dissolving medium, but not much volume. Big particles have more volume, but not as much surface area. So, for a given amount of material, the one with more surface area available will dissolve more quickly.

∙ 11y agosmaller partcals dissolve faster because they have less surface area

How do concentrated and dilute solutions differ from saturated and unsaturated ones?
Nothing more can be added to a saturated solution - the liquid is literally 'full up' with the solute being dissolved, so if you carry on adding the solute, it will not dissolve and the solution will not become any more concentrated. A concentrated solution has a very large amount of the solute in it (there is more solute than solvent), but it has not yet reached the point where no more solute can be dissolved. If you keep adding to it, the solute will dissolve.
How many parts are in a solution?
There are two parts in a solution. One of them is solvent and another one is solute. solvent is the substance which present in large amount. solute is the substance which present in smaller amount.
Which condition is necessary for solid to dissolve?
the molecules of liquids have large intermolecular spaces between them.when a solid(especially salts) is poured in liquid,the molecules of the solid occupy these intermolecular space of the liquid. This is the reason why a solid dissolves in a liquid
How is the surface area of a solid related to its solubility?
A greater surface area means a greater portion of the solid(solute) is in contact with the solvent at a given time. This increases the area in which interaction between the 2 substances can take place, and thus the rate at which the solute dissolves.
Describes a solution with a large amount of solute compared to the amount of solvent?
"Concentrated" if you could still dissolve more solute in the solvent, or "saturated" if this is not possible (because there is so much dissolved already).
How does a particular size affect a soluble solid?
The smaller the particles, the more quickly and easily they dissolve. A powdered solute will dissolve faster than a large piece of the same solute.
What is the large amount of solute?
The "solute" is the substance you are trying to dissolve. The solvent is the substance you are trying to dissolve it in.
What factors affecting the rate of dissolving?
What factors affect the rate of dissolvingHow quickly a substance dissolves in a solvent is unknown. A teaspoon of table sugar will dissolve rapidly in a hot drink. The same amount of sugar will take much more time to dissolve in a glass of ice water. Similarly, table salt dissolves rapidly in water at room temperature. Large pieces of salt, like those used in home water softeners, dissolve much more slowly, which makes this type of salt ideal for use over long periods. The rate of dissolving is affected by three main factors:StirringTemperatureParticle SizeStirring Stirring a solution increases the rate at which a solute dissolves in a solvent. For example, you may have tried to make a soft drink by dissolving flavor crystals in a pitcher of water. The flavor crystals are the solute and water is the solvent. If the package of flavor crystals is poured into the water, dissolving begins, but clumps of powder may remain. To speed up the process, you probably used a spoon to stir the water with the flavour crystals. This results in a more uniform arrangement of flavor crystals and water particles makes dissolving occur more quickly. You can actually see the flavor crystals being stirred until they dissolve in the water. The end result is a solution, as all parts of the soft drink mixture look the same. Temperature Temperature affects the speed at which particles move. Particles move more rapidly at higher temperatures, as heat is transferred by the movement of the particles. Since the rate of dissolving depends on solute particles bumping into solvent particles, when the particles move more rapidly, more solvent and solute particles will bump into one another. In addition, the solvent particles at the edge of a piece of solute will more rapidly carry away the solute particles that they meet. This will quickly spread the solute particles throughout the solvent. With increasing temperature, most solutes dissolve more rapidly in most solvents. This explains, for example, why a teaspoon of sugar dissolves more quickly in a cup of hot tea then in a glass of iced tea.Particle Size Particle size also affects the rate of dissolving. Large particles take longer to dissolve than smaller particles of the same substance. For example, sugar cubes dissolve more slowly than granular sugar, and rock salt dissolves more slowly than table salt. Solvent particles must bump into solute particles for dissolving to occur. Particles of a solvent will contact solute particles at the surface of a clump or crystal of solute particles. Therefore, large pieces of a solute must be broken apart to enable solvent particles to come in contact with solute particles.

Which will dissolve faster a substance with little surface area or the one with a large surface area?
One with a large surface area because the solvent will be able to dissolve more solute simultaneously.
What do surface area and the rate something dissolve have in common?
The more surface area of a solute is exposed to a solvent, the more quickly the solvent can act on the solute, dissociating it if it's ionic. This is why finely grained salt dissolves much more quickly than a large clump of salt.
How do concentrated and dilute solutions differ from saturated and unsaturated ones?
Nothing more can be added to a saturated solution - the liquid is literally 'full up' with the solute being dissolved, so if you carry on adding the solute, it will not dissolve and the solution will not become any more concentrated.

What kind of particle in soil is large and drains quickly?
Sand sized particles.
