# What is one way to increase the rate of dissolving salute in to________ A. Decrease the temperature of the solution B. Let the solute settle to the bottom of the solution C. Stir the solution D. Use a salute with a larger particle size What is the answer?

C. Stir the solution

#### Explanation:

There's 3 main factors you should know that affect dissolution:

• Temperature : The $\textcolor{b l u e}{\text{higher}}$ the temperature, the $\textcolor{b l u e}{\text{more}}$ solute you will dissolve.
• Agitation: The $\textcolor{b l u e}{\text{more agitated}}$ the solution, the $\textcolor{b l u e}{\text{more}}$ solute you will dissolve.
• Particle Size: The $\textcolor{red}{\text{larger}}$ the particle size, the $\textcolor{red}{\text{less}}$ solute you will dissolve.

Given this:

Answer A is incorrect: Decreasing temperature will only decrease the amount of solute you dissolve.

Answer B is incorrect: Allowing the solution to settle means that you are not agitating it, which means you will not dissolve as much solute.

Answer D is incorrect: Larger particles mean that you will dissolve less solute.

Answer C is correct: By stirring, you're agitating the solution, which means you'll dissolve a greater amount of solute.

Hope that helped :)
