1 | VAPOR DIFFUSION, HANGING DROP | 4.5 | 298 | 1.0-1.4 M NaCl, 0.050 M acetate. Crystals soaked in a saturated solution of AziRu containing 2.4 M NaCl in the same buffer. After a few hours, crystals changed their colour to yellow and then green. In a few days they turned to black., pH 4.5, VAPOR DIFFUSION, HANGING DROP, temperature 298K |
