Factors that affect how fast a solid dissolves include surface area of the exposed to the , temperature of the solvent, and stirring.
Surface Area
If the solute is crushed, it will dissolve more quickly because more surface area is exposed to the solvent.
Temperature
The higher the temperature, the faster the particles of the solvent and solute will move and come into contact, which will increase the rate at which the solute dissolves.
Stirring
Stirring or agitating the solvent and solute will increase the speed at which the particles move and come into contact, which will increase the rate at which the solute dissolves.
