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 does an increase in surface area help a solute dissolve more quickly?

Not necessarily just changing the surface area causes the rate to change. Changing the ratio of surface area volume changes the rate at which a solute dissolves in a solvent. If the surface area is larger and the volume of a solute is smaller or the same, then the rate at which the solute dissolves in a solvent increases. If the surface area is smaller and the volume of the solute is larger or the same, then the rate at which the solute dissolves in a solvent decreases.


Why do need to stir the water continuously during heating?

by heating we increase the inter moleculer space of the solvent so the solute particles get in the increased space and by stirring also the same purpoose is served . in short it is done so as to dissolve the solute in the solventHeating will help solutes dissolve in many solvents. For example salt will dissolve in hot water better than cold water.Many chemical reactions either require energy input to initiate a reaction, or they react better at higher energy levels.Endothermic reactions require energy to proceed.Even exothermic reactions may require activation energy to initiate the reactions.Or... many reactions won't run efficiently or completely at cold temperatures.


How do you clean up silly sludge?

What is the solute and solvent of fish sauce in chemistry?

Neiths true:"The Solute is the Substance dissolved into the Solvent"So soy sauce is the total: Solution


Can solubility be increased by stirring?

Solubility can be increased in solvent and by adding more solute.
