What is the acid-ionization constant for HClO2?

What is the acid-ionization constant for HClO2?

The acid-dissociation constant for chlorous acid (HClO2)(HClO2) is 1.1×10−21.1×10−2.

Is ionization constant Ka or KB?

For an aqueous solution of a weak acid, the dissociation constant is called the acid ionization constant (Ka). Similarly, the equilibrium constant for the reaction of a weak base with water is the base ionization constant (Kb).

How is the equilibrium constant for a weak acid?

For an aqueous solution of a weak acid, the dissociation constant is called the acid ionization constant (Ka). Similarly, the equilibrium constant for the reaction of a weak base with water is the base ionization constant (Kb). For any conjugate acid–base pair, KaKb=Kw.

How do you find the Ka of an acid?

Ka from Titration Curve At the equivalence point, the pH of the solution is equivalent to the pKa of the solution. Thus using Ka = – log pKa equation, we can quickly determine the value of Ka using a titration curve.

What is meant by acidity constant Ka?

Solution : Acidity constant `K_(a)` is a measure of the strength of the acid. Obviously greater is the value of `K_(a)`, stronger is the acid.

How is ionization constant Ka related to the strength of an acid?

The larger the Ka, the stronger the acid and the higher the H+ concentration at equilibrium. Like all equilibrium constants, acid–base ionization constants are actually measured in terms of the activities of H+ or OH−, thus making them unitless.

What is Ka vs KB?

The acid dissociation constant (Ka) is a quantitative measure of the strength of an acid in solution while the base dissociation constant (Kb) is a measure of basicity—the base’s general strength. Acids are classified as either strong or weak, based on their ionization in water.

How is Ka and KB related?

The Ka is the acid dissociation constant. The larger the value of Kb, the stronger the base, and the larger the value of Ka, the stronger the acid. By multiplying Ka by Kb, you receive the Kw, or the dissociation constant for water, which is 1.0 x 10^-14.
