weak acids

Postby tatianatumbling_1J » Mon Jun 04, 2018 5:19 pm

Can someone name some of the weak acids the professor listed in class? Also,how can we tell if they are weak? does it have to do with the varge of the molecules?

The example I wrote down for weak acids was CH3COOH molecules and a small portion of acetate ions, CH3COO-

Weak acids are incompletely ionized in a solution, in the example in lecture today it says to setup an equilibrium to calculate concentrations

I wrote down carbonic acid (H2CO3) and benzoic acid (C6H5COOH). Apparently, when there is a carbon present the acid is weaker. In addition, compared to strong acids which dissociate completely, weak acids only dissociate ~1%.
