Why does stirring increase the rate of dissolution?
Understand the Problem
The question is asking about the relationship between stirring and the rate at which a solute dissolves in a solvent. It seeks to understand the scientific principles that explain why agitation can promote faster dissolution, likely involving concepts of particle interaction and surface area exposure.
Answer
Stirring helps distribute the solute particles evenly, increasing the rate of dissolution.
The final answer is that stirring increases the rate of dissolution because it helps distribute the solute particles evenly throughout the solvent, enhancing the contact between solute and solvent molecules.
Answer for screen readers
The final answer is that stirring increases the rate of dissolution because it helps distribute the solute particles evenly throughout the solvent, enhancing the contact between solute and solvent molecules.
More Information
Stirring not only helps to evenly distribute solute particles but also brings fresh solvent molecules into contact with the solute, leading to more effective dissolution.
Tips
A common mistake is to assume that stirring changes the chemical properties of solutes or solvents. It merely mechanically aids the distribution process.
