Final answer:
To convert from Kb to pKa, subtract the negative logarithm (base 10) of Kb from 14.00.
Step-by-step explanation:
To convert from Kb to pKa, you can use the relationship pKa + pKb = 14.00. Since pKb is the negative logarithm (base 10) of Kb, you can find pKa by subtracting the pKb value from 14.00.
For example, let's say the Kb value is 1.0 x 10^-5. To find pKa, first find pKb = -log10(1.0 x 10^-5) = 5. Then subtract this value from 14.00 to get pKa = 14.00 - 5 = 9.00.
Therefore, Kb = 1.0 x 10^-5 corresponds to pKa = 9.00.
