Lab Manual Update

Spent another 4 hours to run different sample solutions for Lab 19.2 revisions.I think I found concentrations that at least give me a 0.8 correlation value.  It also makes use of lover volumes of chemical reagents and generates less waste.

Tomorrow:

I will try to replicate what I did today.

See if I cut down volumes to half

I also found some good labs to test to replace the 30A and 31 empirical formula labs and the Chem 31 Lab 3102.  I will try these two in the next few days.
