CHE 8A Lecture 6: Bronsted Lowry Acids+ Bases, Pka's, What Makes A Stronger Acid?, Functional Group Pka's
Document Summary
It direction of reactions stronger acid gets to be an acid one that"s better at donating ht gets rid of ht stronger an acid is. , the weaker it is as a base easy to donate ht hard for conjugate to accept. Ka measure ability of acid to split up ka - ][ a ha > i lots htt a- stronger acid. [ ha ] c h2o ] had mostly ha weaker acid acid dissociation constant large range for ha lot " I arrhenius ) whichever acid has smaller pka acts as the acid in. Lowry aa "d donating the same ht really tells conjugate base that now good acid is . more comfortable conjugate base is w/ -0 charge easier it is to lose ht . 0 charge larger atoms out more sheildea , less conc . spread. 0 down periodic table get better acid . Electronegativity of atom w/ -0 charge right on periodic table get better acids.
