pka v. ka

[Abigail Menchaca_1H]

What is the difference between pKA and KA?

[JasonKwon_3k]

pKa = -log(ka)

[madawy]

Whenever you see a "p" in front of a value, like pH, pKa, and pKb, it means you're dealing with a -log of the value following the "p". For example, pKa is the -log of Ka. Because of the way the log function works, a smaller pKa means a larger Ka.

[sbeall_1C]

The difference between pKa and Ka is that the pKa is the negative logarithm of Ka. The lower the Ka value, the greater the pKa value, and therefore the stronger the acid.

[zoedfinch1K]

KA is the equilibrium constant with the formula:
KA= [products]/[reactants]

pKA is just the -log of the KA:
pKA= -log[KA]
