Solubility Formula for 1:1 Electrolytes:
| From: | To: |
Solubility calculation for 1:1 electrolytes involves determining the maximum amount of a substance that can dissolve in a solution based on its solubility product constant (Ksp). For 1:1 electrolytes (like NaCl or AgCl), the relationship is mathematically expressed as S = √Ksp.
The calculator uses the solubility formula for 1:1 electrolytes:
Where:
Explanation: This formula applies to 1:1 electrolytes where the dissolution reaction is of the form AB(s) ⇌ A⁺(aq) + B⁻(aq), and the equilibrium constant Ksp = [A⁺][B⁻].
Details: Calculating solubility is essential in chemistry for predicting precipitation reactions, designing chemical processes, and understanding the behavior of ionic compounds in solution.
Tips: Enter the solubility product constant (Ksp) as a positive number. The calculator will compute the solubility in moles per liter (mol/L).
Q1: What are 1:1 electrolytes?
A: 1:1 electrolytes are ionic compounds where the cation and anion have equal but opposite charges, such as NaCl, KCl, or AgCl.
Q2: Does this formula work for all electrolytes?
A: No, this simplified formula S = √Ksp only applies to 1:1 electrolytes. Other stoichiometries require different formulas.
Q3: What units should I use for Ksp?
A: Ksp is dimensionless but represents the product of ion concentrations. Enter the numerical value without units.
Q4: What if my compound has a different stoichiometry?
A: For compounds with different ratios (like 1:2 or 2:3), the solubility calculation requires a different formula that accounts for the stoichiometric coefficients.
Q5: How accurate is this calculation?
A: This calculation provides a theoretical maximum solubility. Actual solubility may vary due to factors like temperature, pH, and the presence of other ions.
