If 10 grams of salt are dissolved in 100 mL of water, which component is the solute?
Salt only
To solve this question, we need to understand the definitions of solute and solvent in the context of solutions in chemistry.
Concepts: Solute and Solvent
- Solute: The substance that is dissolved in another substance. It is usually present in a smaller amount. In this case, the solute is what gets dissolved in the water.
- Solvent: The substance in which the solute is dissolved. It is usually present in a larger amount compared to the solute. Here, water acts as the solvent.
Given the information:
- Amount of salt: 10 grams
- Volume of water: 100 mL
In this mixture, salt is the solute because it is being dissolved in the water. Water serves as the solvent because it is the liquid in which the salt dissolves.
Analysis of Options
- Neither: This would mean that neither water nor salt is the solute, which isn't possible because a solute-solvent relationship exists.
- Water only: Incorrect because water is the solvent, not the solute.
- Both salt and water: Incorrect as only one component acts as a solute in a simple solution.
- Salt only: Correct, as salt is the substance being dissolved.
Thus, the correct answer to the question is: Salt only.
