Feb 3, 2016 · I like to think of it like this: the pKa is the pH at which 50% of the ionizable groups are deprotonated. Anything below the pKa of the group means the group is protonated, (low pH means acidic conditions, and acids give protons) any pH above the pKa is deprotonated (high pH means basic conditions, and bases steal protons)

r/EarlyPKA: Early episodes of PKA and PKN every week.

Aug 2, 2018 · I definitely have. When your 14-17 you find wings disgusting story’s funny. But like most of us who have grown up watching PKA, you mature and realise he’s just a sad man telling lies and being disgusting for shock value.

Sep 15, 2012 · The pKa is simply the pH at which half the acid is in its protonated form. For strong acids like the ones you listed, even at 0 pH less than half of the acid will be protonated. A strong acid really 'wants' to be dissociated and you need a very concentrated acidic solution to convince it …

Apr 15, 2014 · As since Ka values span many orders of magnitude, in order to avoid unwieldy scientific notation,, pKa is frequently given instead, where: pKa = -log(Ka) Thus, pKa is just a more compact way to state the Ka of an acid. Because it is the negative log (base 10) of the Ka, the lower the pKa, the stronger the acid.

May 19, 2023 · A LOW pKa is a STRONG acid, so a HIGH pKa is a WEAK acid. I like to remember that pKa and Ka are opposites: if pKa is low, Ka will be high. pH: tells you whether something is acidic or basic. acidic conditions would range from 0 - 6, basic controls would range from 8 - 14, and neutral is always 7. there are a few ways you can think of pH. there ...

Jan 2, 2018 · PKA 34 w/ Whiteboy and Blade - Of the OG shows and guests, these two were always the most hilarious PKA 336 & 347 w/ Dick - The guys just all worked really well together PKA 346 w/ Jordan Peterson - Quite different, but again, the guys did a good job for who the guest was PKA 335, 315 w/ Steve Hofstetter and honestly every episode with him.

Nov 16, 2022 · Thus pKa 2 will be a value that is part of the pI calculation. If we move past the next pKa value (3), we will deprotonate the side chain to COO-, adding another negative charge, making the net charge -1. Now we have stopped being a zwitterion and thus this will be the next and final pKa value to be used for pI calculations. pI = 2+3/2 =2.5

Aug 11, 2017 · I assume it means the pKa of the conjugate acid of the most basic functional group in the molecule, which is probably a ketone. Negative pKa's mean the group is strongly acidic. HCl has a pKa of -7, which is not surprising, since it is a strong acid.
