- 1.74 × 10-5 is the ionizing constant (Ka) of acetic acid (CH3COOH).
- The ionizing constant is a measure of the strength of an acid in solution.
- Acetic acid is a weak acid, and its ionizing constant reflects its partial ionization in water.
- The value indicates the extent to which acetic acid dissociates into its ions in aqueous solution.
Additional Information
- The dissociation of acetic acid in water can be represented by the equation: CH3COOH ⇌ CH3COO- + H+.
- Ka is calculated using the concentrations of the products and reactants at equilibrium: Ka = [CH3COO-][H+]/[CH3COOH].
- The low value of Ka for acetic acid indicates that it does not ionize completely in water, characteristic of weak acids.
