There was a mistake in one of the numbers I gave in the Cr^3+, Sn^2+
precipitation problem in the pre-recorded lectures. The conc. of OH- for
the Cr(OH)3 at equilibrium, just before ppt of the Cr(OH)3, was given as
3.4 x 10^-11 M. It should be 2.5 x 10^-10 M. That's in part (a) in the
notes.
I've made corrections to the example and have attached them.
This was done correctly in the in-person lectures.
