Depending on the physical states of solvents and solutes , there are _______ types of solutions.

Options

A. five
B. seven
C. nine
D. twelve

Answer

To determine the number of types of solutions based on the physical states of solvents and solutes, we can follow these steps:

### Step 1: Understand the Definitions
- **Solute**: The substance that is present in a lesser amount in a solution.
- **Solvent**: The substance that is present in a greater amount in a solution.

### Step 2: Identify the Physical States
There are three physical states of matter:
1. Solid
2. Liquid
3. Gas

### Step 3: Classify Solutions Based on Solvent and Solute States
We can categorize solutions based on the combinations of solute and solvent states.

1. **Solid Solvent**:
- Solid solute (e.g., salt in solid form)
- Liquid solute (e.g., mercury in solid form)
- Gaseous solute (e.g., air in solid form)

2. **Liquid Solvent**:
- Solid solute (e.g., sugar in water)
- Liquid solute (e.g., alcohol in water)
- Gaseous solute (e.g., carbon dioxide in water)

3. **Gas Solvent**:
- Solid solute (e.g., smoke in air)
- Liquid solute (e.g., mist in air)
- Gaseous solute (e.g., oxygen in air)

### Step 4: Calculate the Total Types of Solutions
- From the **solid solvent**, we have 3 types of solutions.
- From the **liquid solvent**, we have 3 types of solutions.
- From the **gas solvent**, we have 3 types of solutions.

Adding these together gives us:
\[ 3 \text{ (solid solvent)} + 3 \text{ (liquid solvent)} + 3 \text{ (gas solvent)} = 9 \text{ types of solutions} \]

### Conclusion
Thus, depending on the physical states of solvents and solutes, there are **9 types of solutions**.
