Percentage protonated

Postby Deepika Pugalenthi 1A » Fri Jan 18, 2019 12:15 pm

What is the significance of finding the percentage protonated? Does it help check if the values are valid or plausible?

The percentage protonated is just another way of indicating the power of a base. If the percent protonated was close to 100, that would mean that you have a strong base because all, or almost all, of the base has received a proton from water and become the conjugate acid. A low percent protonation indicates that a lot of the base still exists in an unprotonated form and is therefore not a strong base.

Further, Lavelle mentioned for weak acid/base it should be below 5% protonated as a way to check if you did the problem right.
