Degree of Saturation Formula:
| From: | To: |
The Degree of Saturation (S) is a measure of how much solute is dissolved in a solution compared to the maximum amount that can be dissolved (solubility limit) at a given temperature and pressure. It's expressed as a percentage.
The calculator uses the degree of saturation formula:
Where:
Explanation: The formula compares the current concentration of a solution to its maximum possible concentration at saturation.
Details: Knowing the degree of saturation helps predict whether a solution is undersaturated, saturated, or supersaturated, which is crucial for crystallization processes, chemical reactions, and material solubility studies.
Tips: Enter both current concentration and solubility limit in g/L. Both values must be positive numbers. The solubility limit is temperature-dependent, so ensure you're using the correct value for your conditions.
Q1: What does 100% saturation mean?
A: 100% saturation means the solution contains exactly the maximum amount of solute that can be dissolved at the current conditions. Any additional solute will not dissolve.
Q2: Can saturation exceed 100%?
A: Yes, solutions can become supersaturated (S > 100%) under certain conditions, though these are typically unstable and may precipitate solute.
Q3: How does temperature affect saturation?
A: For most solids, solubility increases with temperature. For gases, solubility typically decreases with increasing temperature.
Q4: What's the difference between solubility and saturation?
A: Solubility is the maximum amount that can dissolve, while saturation describes how close a solution is to that maximum.
Q5: Why use g/L units?
A: g/L is convenient for many practical applications, but you can use any consistent units as long as both concentration and solubility limit use the same units.
