Two acids have the following pKa values:3.85 and 5.65. what are the corresponding Ka values?
pKa and pKb are analogous to pH and pOH.
pKa = -log Ka.
Plug in the negative value of Ka on your calculator and hit the 10x button.
For pKa of 3.85 you should find 1.41 x 10^-4.
thanks again
To find the corresponding Ka values for the given pKa values, we can use the formula:
Ka = 10^(-pKa)
Let's calculate the values:
For the acid with a pKa of 3.85:
Ka = 10^(-3.85)
= 1.74 x 10^(-4) or approximately 0.000174
For the acid with a pKa of 5.65:
Ka = 10^(-5.65)
= 3.55 x 10^(-6) or approximately 0.00000355
Therefore, the corresponding Ka values are approximately 0.000174 and 0.00000355 for the acids with pKa values of 3.85 and 5.65, respectively.
