Definition: This calculator determines the concentration of a second acid based on the relative strength of two acids and their degrees of dissociation.
Purpose: It helps chemists and students compare acid strengths and concentrations in chemical equilibrium problems.
The calculator uses the formula:
Where:
Explanation: The formula relates the concentrations of two acids through their relative strength and dissociation characteristics.
Details: Accurate acid concentration calculations are essential for pH determination, buffer preparation, and chemical reaction stoichiometry.
Tips: Enter all required values (must be > 0). Degrees of dissociation should be between 0 and 1.
Q1: What is degree of dissociation?
A: It's the fraction of acid molecules that dissociate into ions in solution (ranges from 0 to 1).
Q2: How is relative strength determined?
A: Relative strength is the ratio of hydrogen ion concentrations or equilibrium constants of the acids.
Q3: Can I use molarity (M) instead of mol/m³?
A: Yes, since 1 M = 1 mol/L = 1000 mol/m³, the units will cancel out in the ratio.
Q4: What if degree of dissociation is very small?
A: The calculator still works, but very small values (near 0) indicate weak acids.
Q5: Does temperature affect this calculation?
A: Yes, since degree of dissociation is temperature-dependent, ensure all values are for the same temperature.
