When some of the sugar added to iced tea remains undissolved on the bottom of the glass, the solution can be described as:
**Options:**
- A. dilute
- B. polar
- C. nonpolar
- D. saturated
- E. unsaturated
### Explanation
This question tests the understanding of solution chemistry. When sugar remains undissolved at the bottom of the glass, it indicates that the solution cannot dissolve any more sugar at a given temperature, meaning it is **saturated**. The correct answer is:
- **D. saturated**
A saturated solution contains the maximum amount of solute that can be dissolved in the solvent at a specific temperature and pressure.

The student will collect water samples from the school drinking fountain, home kitchen tap, and a nearby river. To test for lead, the student will use a solution of iodide ion. The student obtains some distilled water (known not to contain lead) and adds the iodide ion; the water remains clear. Next the student obtains a solution known to contain lead from the chemistry laboratory; when iodide ion is added to this sample, a bright yellow solid forms. The Negative Control for this experiment is... distilled water distilled water with the iodide ion solution with lead solution with lead with the iodide ionarrow_forward
