Dissociation Constant Ka given Initial Concentration of Weak Acid and Degree of Dissociation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Dissociation Constant of Weak Acid = (Initial Concentration*(Degree of Dissociation^2))/(1-Degree of Dissociation)
K_a = (C₀*(𝝰^2))/(1-𝝰)
This formula uses 3 Variables

Variables Used

Dissociation Constant of Weak Acid - The Dissociation Constant of Weak Acid is a quantitative measure of the strength of a weak acid in solution.
Initial Concentration - (Measured in Mole per Cubic Meter) - The Initial concentration is the abundance of a constituent divided by the total volume of a mixture before diffusion or reaction.
Degree of Dissociation - The Degree of Dissociation is the extent of generating current carrying free ions, which are dissociated from the fraction of solute at a given concentration.

STEP 1: Convert Input(s) to Base Unit

Initial Concentration: 0.3 Mole per Liter --> 300 Mole per Cubic Meter (Check conversion here)
Degree of Dissociation: 0.35 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

K_a = (C₀*(𝝰^2))/(1-𝝰) --> (300*(0.35^2))/(1-0.35)

Evaluating ... ...

Explain Ostwald’s dilution law.

Ostwald’s dilution law is a relationship proposed in 1888 by Wilhelm Ostwald. Ostwald’s dilution law describes the dissociation constant of the weak electrolyte with the degree of dissociation (α) and the concentration of the weak electrolyte. Ostwald’s dilution law states that only at infinite dilution the weak electrolyte undergoes complete ionization.
