Marie C. Haulait-Pirson Solubility, Solubility data series (1) was saturated by storing over a layer of (2) in a brown glass bottle without any agitation. The bottle was sealed with serum cap and completely submerged in the water-bath for seven days. A 20 mL sample was withdrawn with a silicone-hydrophobized hypodermic syringe. Stabilized Karl Fischer reagent diluted to a titer of 1.0-1.3 mg (2)/mL was used to titrate (2) in (1) directly in the presence of methanol to a 'dead-stop' end-point using a Beckman KF3 automatic titrimeter.
