Rate of solution is how fast a substance dissolves in a solution. Factors determining the rate of solution are:
- The size of the particles
- When a solute dissolves, only the surface of the solute comes in contact with the solvent. Therefore, the more the surface area of the solute, the faster it dissolves. This is why sugar powder dissolves faster than chunks of sugar.
- Stirring
- When you're dealing with solid and liquid solutes, stirring brings fresh parts of the solvent into contact with the solute.
- Amount of solute already dissolved
- As the solvent approaches the point where it's Saturation (chemistry), it can hold less and less solute.
- Temperature
- Increasing the temperature also generally increases the amount of solute the solvent can hold (solid and liquid solutes).
