What speeds up dissolving?

Answer 1

To speed up the dissolving of a solute you can, among many options:

• Heat up the mixture
• Stir the mixture
• Add more solute, then filter off the excess
• Crush the solute to give it a greater surface area

Answer 2

Increasing the surface area of the solute will speed up the dissolving process - For example, 10g of tiny salt crystals will dissolve much faster than a 10g solid salt crystal in water because more of the salt is exposed to the water all at once. In the larger crystal, the water is only in contact with the salt on the outside surface. If it is broken up into smaller pieces, nearly all of the salt is in contact with water at once and can dissolve very quickly.

Increasing the temperature of the water will also speed up dissolving. Think of mixing cocoa powder into cold milk vs. hot milk (to make Hot Chocolate) - which takes less time to mix? Temperature is a measure of the average kinetic energy of the molecules in a substance, or in simple terms, how fast the H20 molecules are moving on a microscopic scale. In ice, there is little motion. In boiling water, there is LOTS of motion. In hot water, the quickly moving molecules bump into the solute at a fast rate and dissolve it in less time than those in cold water.

Answer 3

Several factors can speed up the process of dissolving, including increasing temperature, stirring or agitation, reducing particle size, and increasing surface area of the solute. Additionally, using a solvent that can effectively interact with and break down the solute can also facilitate faster dissolution.

Answer 4

To help speed up the rate of dissolving you could:

Stir your solute faster!

Heat!

Crush before dissolving!

Use hot water instead of using heat!

Answer 5

Stirring, heat, add more liquid .. xo- steph
