Initial Concentration of Weak Base given Dissociation Constant Kb and Degree of Dissociation Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
Dissociation Constant of Weak Base - The Dissociation Constant of Weak Base is the dissociation constant for an aqueous solution of a weak base.
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

Dissociation Constant of Weak Base: 9 --> No Conversion Required
Degree of Dissociation: 0.35 --> No Conversion Required

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.
