Question

Identify the best solvent type for each substance below.(5 points) Polar solvent Nonpolar solvent
Skin oils
Natural peanut oil
Butter
Fruit juice
Potassium chloride, KCl

Answer 1

To identify the best solvent type for each substance, we can categorize them based on their polarity:

1. **Skin oils** - Nonpolar solvent (Skin oils are predominantly made of nonpolar molecules, so nonpolar solvents would dissolve them best).

2. **Natural peanut oil** - Nonpolar solvent (Peanut oil is primarily made up of nonpolar triglycerides, making nonpolar solvents more effective).

3. **Butter** - Nonpolar solvent (Butter is composed of fats, which are mainly nonpolar, making nonpolar solvents more appropriate).

4. **Fruit juice** - Polar solvent (Fruit juice consists largely of water and includes various polar compounds, making polar solvents suitable).

5. **Potassium chloride, KCl** - Polar solvent (KCl is an ionic compound that dissolves well in polar solvents like water due to ion-dipole interactions).

To summarize:
- Skin oils: Nonpolar solvent
- Natural peanut oil: Nonpolar solvent
- Butter: Nonpolar solvent
- Fruit juice: Polar solvent
- Potassium chloride, KCl: Polar solvent
