Re: pKa
An acid is stronger if it has a lower pKa. It's similar to how a lower pH means an acid is stronger.

Re: pKa
Lower pKa means a less negative Ka which means that there is a high amount of dissociation and thus a stronger acid.

Re: pKa
pKa = -log Ka; so according to that equation, the lower the pKa is, the higher the Ka will be meaning it is a stronger acid. The higher the pKa is, the lower the Ka will be meaning it will be a weaker acid.
