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.
A 2.14g sample of sodium hypoiodite is dissolved in water to make 1.25 L of solution the solution pH is 11.32 what is the KB for the hypoiodite ion?
To find the pOH from the given pH value (pH = 11.32), subtract the pH from 14 (pH + pOH = 14) to get pOH. Then use the pOH to find the hydroxide ion concentration in the solution. Finally, use the hydroxide ion concentration along with the initial concentration of hypoiodite ion to determine the KB value for the hypoiodite ion using the expression for the KB of a weak base.
What is the molarity of ammonia solution if the pH is 11.6 and the Kb is 1.8x10-5?
To find the molarity of ammonia solution, first calculate the concentration of OH- ions in the solution using the pH value. From there, use the Kb value to find the concentration of NH3. Finally, convert the concentration of NH3 to molarity to get the answer.
What is better the h2o crystal necklace or the h2o locket?
The choice between the H2O crystal necklace and the H2O locket ultimately depends on personal preference. The crystal necklace may be more versatile in terms of styling, while the locket can hold sentimental value as it can encase a small item or photo. Choose based on which design resonates more with you or the intended wearer.
What is the boiling point of a 2.86 m solution of ammonium nitrate NH4NO3 Assume that the solvent is water which has a Kb of 0.51ºC m and a boiling point of 100.0ºC?
To find the boiling point elevation of the solution, you can use the formula: ΔTb = i * Kb * m, where i is the van't Hoff factor, Kb is the ebullioscopic constant, and m is the molality of the solution. Plug in the values given and solve for ΔTb. Then, add this value to the boiling point of the solvent (100.0°C) to find the boiling point of the solution.

kb=[C5H5NH+][OH-]______[C5H5N]
What is the KB expression for aniline?
The KB expression for aniline c6h5nh2 is: For C6H5NH2 + H2O >< C6H5NH3+ + OH-Kb = 4.3 x (10 ^ -10) = [C6H5NH3+][OH-] / [C6H5NH2]
What is the KB expression for aniline c6h5nh2?
The KB expression for aniline c6h5nh2 is: For C6H5NH2 + H2O >< C6H5NH3+ + OH-Kb = 4.3 x (10 ^ -10) = [C6H5NH3+][OH-] / [C6H5NH2]
What is Kb for CH3NH2(aq) plus H2O(I) CH3NH3 plus (aq) plus OH-(aq)?
Kb = [CH3NH3 +] [OH-] / [CH3NH2]
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.
What Kb value represents the weakest base?
Kb = 3.8 10-10
What is KB for c5h5n aq h2o l c5h5nh aq oh aq?
Kb=c5h5nh+oh- / c5h5n (apex.)
What is the pKa value of H2O?
The pKa value of H2O is approximately 15.7.
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 is the KB value for NAOH?
Kb = 55 It is a very strong base therefore it completely dissociates.
