Which of following KB values represent the strongest base?

Kb = 1.8 x 10-5 (apple x)


What Kb value represents the weakest base?

Kb = 3.8 10-10


Does a strong base have a lower Kb than a weak base?

No, a strong base has a higher Kb (base dissociation constant) than a weak base due to its greater ability to ionize in solution. Strong bases like sodium hydroxide have high Kb values, indicating high ionization. Weak bases have lower Kb values because they only partially ionize in solution.


What is Kb for C5H5N(aq) H2O(l) C5H5NH (aq) OH-(aq)?

The Kb for C5H5N (pyridine) is 1.7 x 10^-9. This value indicates the strength of the base in solution, with lower values suggesting a weaker base and higher values indicating a stronger base.


An acid has Ka 3.1 10 10 What is the Kb for the conjugate base of this acid at 25 C Kw 1.0 10 14 at 25 C?

To find the Kb for the conjugate base, you can use the relationship Kw = Ka * Kb. Rearrange the equation to solve for Kb: Kb = Kw / Ka. Plugging in the values, you get Kb = (1.0 x 10^-14) / (3.1 x 10^-10) = 3.23 x 10^-5.


An acid has Ka 2.5 10 4 What is the Kb for the conjugate base of this acid at 25 C Kw 1.0 10 14 at 25 C?

Since Kw = Ka * Kb, we can rearrange the equation as Kb = Kw / Ka. Plugging in the values, Kb = (1.0 x 10^-14) / (2.5 x 10^-4) = 4.0 x 10^-11. This is the Kb for the conjugate base of the given acid.


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 is the KB value for NAOH?

Kb = 55 It is a very strong base therefore it completely dissociates.


What is KB for cn aq h2o l hcn aq oh aq?

Kb=[HCN][OH-]/[CN-]


What is KB for cn- aq h2o l hcn aq oh-aq?

The Kb for CN- (aq) is the equilibrium constant for the reaction of CN- with water to form HCN (aq) and OH- (aq). It represents the strength of the base CN- in solution. It can be calculated by taking the concentration of the products (HCN and OH-) and dividing by the concentration of CN- at equilibrium.


What is the equation for the base ionization constant for NH3?

The base ionization constant (Kb) for NH3 can be represented by the equation: Kb = [NH4+][OH-] / [NH3].


What is always true pf a weak base?

A weak base will always partially ionize in solution and generate fewer hydroxide ions compared to a strong base. This means that a weak base will have a lower pH compared to a strong base at the same concentration. Weak bases also have higher Kb values compared to strong bases.
