If the Ka of an acid is 4.4 x 10^-7 then Kb for its base would be
The Kb for methyl oragne is
The Kb for nitrite ion is
To find the Kb for a base related to an acid with a given Ka value, you can use the equation Kw = Ka x Kb.
Kw is the equilibrium constant for water, which is 1.0 x 10^-14 at 25°C.
If the Ka of an acid is 4.4 x 10^-7, we can substitute the values into the equation to solve for Kb:
1.0 x 10^-14 = (4.4 x 10^-7) x Kb
Divide both sides by 4.4 x 10^-7 to isolate Kb:
Kb = (1.0 x 10^-14) / (4.4 x 10^-7)
Kb ≈ 2.27 x 10^-8
The Kb value for the base related to the acid with a Ka of 4.4 x 10^-7 is approximately 2.27 x 10^-8.
To determine the Kb value for methyl orange or the nitrite ion, specific data regarding their respective acid dissociation constants (Ka) would be needed. Without this information, it is not possible to calculate their Kb values.
