Solubility of a sustance is its

Options

A. maximum amount that can be dissolved in a specified amount of solute at a different temperature
B. minimum amount that can be dissolved in a specified amount of solute at a different temperature
C. maximum amount that can be dissolved in a specified amount of solvent at a specified temperature
D. minimum amount that can be dissolved in a specified amount of solvent at a specified temperature

Answer

**Step-by-Step Text Solution:**

1. **Understanding Solubility**: Solubility refers to the maximum amount of a solute that can dissolve in a given amount of solvent at a specific temperature. This definition is crucial because it highlights that solubility is not a fixed value; it can change with temperature.

2. **Identifying Key Components**:
- **Solute**: The substance that is being dissolved.
- **Solvent**: The substance in which the solute is dissolved.
- **Specific Temperature**: Solubility is measured at a particular temperature, as temperature can significantly affect how much solute can dissolve.

3. **Analyzing the Options**:
- The question provides multiple options regarding the definition of solubility. We need to evaluate them based on our understanding.
- **Option 1**: "Maximum amount that can be dissolved at a specific amount of solute." This option is incorrect because it does not mention the solvent and misrepresents the relationship between solute and solvent.
- **Option 2**: "Different temperature is mentioned." This option is also incorrect because solubility must be discussed at a specific temperature, not varying temperatures.
- **Option 3**: "Maximum amount that can be dissolved at a specific amount of solvent at a specific temperature." This option correctly describes solubility, as it specifies both the solvent and the temperature.

4. **Conclusion**: Based on the analysis of the options, the correct definition of solubility is given by Option 3.

**Final Answer**: The solubility of a substance is the maximum amount that can be dissolved in a specific amount of solvent at a specific temperature.
