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 does stirring surface area and temperature affect dissolving?

To dissolve something, usually you stir it or break it up into smaller pieces. This is because, with increased surface area, there is more area for the solvent to work on the substance. Further, by heating something up usually it breaks bonds, causing something to dissolve more readily.


Which will dissolve faster a substance with little surface area or the one with a large surface area?

A substance with a larger surface area will dissolve faster because it provides more contact points for the solvent to interact with, leading to a faster rate of dissolution compared to a substance with little surface area.


How fast does dissolve?

15 minutes


How do you get a solute to dissolve more quickly?

more surface area. crushing or grinding will help it dissolve as well as heat depending on what you're working on.


How fast do solid dissovle in water?

The rate at which solids dissolve in water depends on factors such as temperature, surface area of the solid, agitation, and the solubility of the substance. Generally, smaller particles dissolve faster due to increased surface area for interaction with the solvent.


Why does a sugar cube take longer to dissolve than a crystal sugar in hot tea?

The speed at which something dissolves is a function of its surface area. A spoon of sugar and a sugar cube may have the same mass, but the tiny crystals in the spoon of sugar have a cumulative surface area much larger than that of the cube.


Will alka-seltzer dissolve faster in half?

Substances dissolve more quickly when more surface area is exposed. By cutting an alka-seltzer in half, you are exposing more surface area to the solvent (water). It would dissolve even more quickly if it were cut into more pieces or crushed into a fine powder.


Why does crushing help a solid solute dissolve?

The rate of dissolution of a solid is dependent on the surface area reaction. By crushing the cube, the surface area is greatly increased, thus increasing the rate of dissolution.


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.


Which area is not common in an area of karst topography?

Surface drainage systems.


Why do larger sugar grains take longer to dissolve?

Larger sugar grains have less surface area exposed to the surrounding liquid, so it takes longer for the liquid to penetrate and break down the sugar crystals. As a result, the larger grains dissolve more slowly compared to finer sugar grains which have more surface area available for the liquid to act on.


What happens to the greatest common factor of the cylinders' surface area if its radius is squared?

Nothing. The cylinder's surface area does not have a GCF.
