What is the primary purpose of stirring a seawater solution during a chemical experiment?

• A. To increase the temperature of the solution
• B. To prevent evaporation of water
• C. To ensure uniform distribution of dissolved substances
• D. To decrease the concentration of salts

Answer: (C)

Verified step by step guidance

1. Understand that stirring a solution primarily helps in mixing the components evenly throughout the solution.
2. Recognize that in a seawater solution, there are dissolved salts and other substances that need to be uniformly distributed for accurate experimental results.
3. Note that stirring does not significantly increase the temperature of the solution; temperature changes are usually controlled separately.
4. Realize that stirring does not prevent evaporation; evaporation depends on factors like temperature and surface area, not stirring.
5. Conclude that the main purpose of stirring is to ensure uniform distribution of dissolved substances, which helps maintain consistent concentration throughout the solution.
