Which term describes a solution having a very well-known concentration of solute?

• A. Supersaturated solution
• B. Standard solution
• C. Dilute solution
• D. Saturated solution

Answer: (B)

Verified step by step guidance

1. Understand the meaning of each term related to solution concentration:
2. A supersaturated solution contains more solute than can normally dissolve at a given temperature, making it unstable.
3. A saturated solution contains the maximum amount of solute that can dissolve at a specific temperature, with undissolved solute present.
4. A dilute solution has a relatively small amount of solute compared to solvent, but its concentration is not necessarily well-known or standardized.
5. A standard solution is a solution with a precisely known concentration of solute, often prepared for use in quantitative chemical analysis.
