Strong Acids

Postby Nicole Garrido 2I » Sun Dec 02, 2018 10:43 pm

Why do strong acids produce more protons than a weak acid? The process.

The definition of a strong acid is that they completely dissociate in solutions and thus, they give off more protons. Weak acids may not completely dissociate and/or dissociate less than strong acids so they won't give off as many protons.

Strong acids produce more protons of H+'s because they are almost completely ionized in solution. HBr, HCl, and HI are some examples of strong acids. Also, in today's lecture, Lavelle talked about how longer bonds associated with larger molecules become increasingly strong acids because the bonds are more easily broken and thus H+ are given off.

You can compare the values of Ka and pKa. For Ka, the larger the Ka, the greater the acidity; the smaller the Ka, the less the acidity. For pKa, the larger the pKa, the less the acidity; the smaller the pKa, the greater the acidity.

Hope this helps!

That helps! my only issue is if we are unsure of the Ka. Should we just go off of electronegativity and size of the atom? This still confuses me a little bit.
