I just bought a new batch of what was supposed to be potassium oxalate.
I knew something was wrong when I could dissolve the normal 33 parts to 100
parts of water.
I decided to test it anyway, and to my surprise the number of visible steps
from a printed Stouffer scale was reduced by 1/2, ceteris paribus.
Any ideas?
