What is the Ka value of NaOH?
The Ka value is a measure of the strength of an acid in solution, not a base like NaOH. Instead, the strength of a base is typically measured using the Kb value. However, if you are asking about the dissociation constant of NaOH in water, it would be the Kw value, which is equal to 1.0 x 10^-14 at 25 degrees Celsius.
What is the relationship between Ka and Kb values, and how can you determine Ka if you know Kb?
The relationship between Ka and Kb values is that they are related by the equation Kw Ka Kb, where Kw is the ion product of water. If you know the Kb value, you can determine the Ka value by rearranging the equation to solve for Ka.
What is the value of Kb for its conjugate base CN?
The Kb value for the conjugate base CN- (cyanide ion) is 2.5 x 10^-5.
What kind of solution would have a Kb value that is much greater then 1?
A solution with a Kb value much greater than 1 would be considered a strong base solution. This indicates that the base is more likely to fully dissociate in water, resulting in a high concentration of hydroxide ions and a higher pH. Examples include solutions of sodium hydroxide (NaOH) or potassium hydroxide (KOH).
What is the pH value of concentrated NaOH?
As NaOH is a strong base I would not be surprised to see a 14 pH at least.
What is the accepted Ka value for sodium hydroxide?
The accepted Ka value for sodium hydroxide (NaOH) is not applicable, as NaOH is a strong base and completely dissociates in water. Instead, the equilibrium constant Kb (base dissociation constant) is typically used for strong bases. The Kb value for NaOH is approximately 1 x 10^-15.
What is the Ka value of NaOH?
The Ka value is a measure of the strength of an acid in solution, not a base like NaOH. Instead, the strength of a base is typically measured using the Kb value. However, if you are asking about the dissociation constant of NaOH in water, it would be the Kw value, which is equal to 1.0 x 10^-14 at 25 degrees Celsius.
What kind of solution would have Kb value that is much greater than 1?
A solution with a Kb value much greater than 1 indicates that it is a strong base, as Kb represents the base dissociation constant. In such solutions, the base dissociates significantly in water, producing a high concentration of hydroxide ions (OH⁻). Examples include strong bases like sodium hydroxide (NaOH) and potassium hydroxide (KOH), which completely ionize in solution.
What Kb value represents the weakest base?
Kb = 3.8 10-10
What is the relationship between Ka and Kb values, and how can you determine Ka if you know Kb?
The relationship between Ka and Kb values is that they are related by the equation Kw Ka Kb, where Kw is the ion product of water. If you know the Kb value, you can determine the Ka value by rearranging the equation to solve for Ka.
What is the value of Kb for its conjugate base CN?
The Kb value for the conjugate base CN- (cyanide ion) is 2.5 x 10^-5.
What solution would have Kb value that is much greater than 1?
A solution with a Kb value much greater than 1 would typically be a strong base, such as sodium hydroxide (NaOH) or potassium hydroxide (KOH). These bases fully dissociate in water, leading to a high concentration of hydroxide ions (OH⁻) and a strong tendency to accept protons. As a result, the equilibrium constant for the base ionization reaction (Kb) is significantly greater than 1, indicating a strong propensity for the base to react with water and form hydroxide ions.
What kind of solution would have a Kb value that is much greater then 1?
A solution with a Kb value much greater than 1 would be considered a strong base solution. This indicates that the base is more likely to fully dissociate in water, resulting in a high concentration of hydroxide ions and a higher pH. Examples include solutions of sodium hydroxide (NaOH) or potassium hydroxide (KOH).

What is the relationship between the Ka and Kb values in a chemical equilibrium system?
The Ka and Kb values in a chemical equilibrium system are related by the equation Kw Ka Kb, where Kw is the ion product constant of water. This relationship shows that as the Ka value increases, the Kb value decreases, and vice versa.
What kind of solution would have a Kb value that is much greater than one?
A solution with a Kb value much greater than one indicates that it is a strong base. This means that the base completely dissociates in water, resulting in a high concentration of hydroxide ions (OH⁻). Such solutions typically consist of strong alkali metals, like sodium hydroxide (NaOH) or potassium hydroxide (KOH), which readily accept protons from water, significantly increasing the pH.
Which of following KB values represent the strongest base?
Kb = 1.8 x 10-5 (apple x)
