The acid dissociation constant for an acid dissolved in water is equal to the?
The acid dissociation constant (Ka) for an acid dissolved in water is the equilibrium constant for the dissociation reaction of the acid into its ion components in water. It represents the extent of the acid's ionization in water.
What is the relationship between the equilibrium constant (Keq) and the acid dissociation constant (Ka)?
The equilibrium constant (Keq) is the ratio of products to reactants at equilibrium in a chemical reaction, while the acid dissociation constant (Ka) specifically refers to the dissociation of an acid in water. The relationship between Keq and Ka is that Ka is a specific type of equilibrium constant for acid dissociation reactions. In other words, Ka is a special case of Keq for acid-base reactions.
How are the equilibrium constants Ka and Kb related in a chemical reaction?
In a chemical reaction, the equilibrium constants Ka and Kb are related by the equation Ka x Kb Kw, where Kw is the equilibrium constant for water. This relationship shows that the product of the acid dissociation constant (Ka) and the base dissociation constant (Kb) is equal to the equilibrium constant for water.
What is the relationship between the equilibrium constants Kb and Ka in a chemical reaction?
The equilibrium constants Kb and Ka in a chemical reaction are related by the equation Ka Kb Kw, where Kw is the equilibrium constant for water. This relationship shows that the product of the acid dissociation constant (Ka) and the base dissociation constant (Kb) is equal to the equilibrium constant for water.
What is the dissociation constant k of pure water?
The dissociation constant of pure water is 1.9E-5.

Which effect can explain increase in dissociation of acetic acid on addition of naoh?
The increase in dissociation of acetic acid upon addition of NaOH can be explained by Le Chatelier's principle. The additional NaOH added reacts with the acetic acid to form acetate ions and water, shifting the equilibrium of the acetic acid dissociation reaction to the right to replace the consumed acetic acid. This results in increased dissociation of acetic acid to maintain equilibrium.
What is an acid dissociation constant?
The acid dissociation constant (Ka) is a measure of how well an acid donates its hydrogen ions in a solution. It is the equilibrium constant for the dissociation of an acid in water into its ions. A high Ka value indicates a strong acid, while a low Ka value indicates a weak acid.
The acid dissociation constant for an acid dissolved in water is equal to?
The acid dissociation constant (Ka) for an acid dissolved in water is equal to the ratio of the concentration of the products (H+ and the conjugate base) over the concentration of the reactant (the acid). It represents the extent of dissociation of the acid in water.
What is the base dissociation constant for a weak base at equilibrium B H2O BH OH?
The base dissociation constant (Kb) for a weak base is the equilibrium constant for the reaction of the base with water to produce hydroxide ions. In this case, the expression for Kb would be [OH-][BH]/[B].
Does acetic acid dissociate in water and what are the products of this dissociation?
Yes, acetic acid does dissociate in water. The products of this dissociation are hydrogen ions (H) and acetate ions (CH3COO-).
If 0.1MHAC is titrated with 0.1MNaoh and the dissociation constant ka of acetic acid is 1.8210-5 and the solubility product of water is 110-14 what is the initial pH of the acid?
To find the initial pH of the acetic acid solution, you would need to use the dissociation constant (Ka) of acetic acid. The initial pH of acetic acid can be calculated using the formula pH = 0.5 * (pKa - log[C]), where pKa is the negative logarithm of the dissociation constant and [C] is the initial concentration of the acid. With the given Ka value of 1.82 x 10^-5 for acetic acid, you can determine the initial pH of the solution.
Why can the concentration of water be ignored in the equilibrium expression for water?
The concentration of water remains relatively constant compared to other reactants/products in solution, so it does not significantly affect the equilibrium constant. Additionally, water is a solvent that is usually present in large excess, so changes in its concentration have minimal impact on the equilibrium position.
