Turning Water Into a Tool: From Degradation Pathways to Functional Engineering in Halide Perovskites

open access: yesAdvanced Materials Technologies, EarlyView.
Water exhibits a threshold‐dependent dual role in lead halide perovskites, acting either as a degradation trigger or as a powerful tool for defect passivation, recrystallization, and structural engineering. This review discusses how controlled water‐mediated interactions govern stability, dimensionality, and optoelectronic performance, providing ...

Dissociation constants of thymolphthalexone

Talanta, 1979
For the dissociation constants of thymolphthalexone the following values have been found: pK(3) = 7.03 +/- 0.02, pK(4) = 8.05 +/- 0.09 (by potentiometric titration), pK(5) = 10.83 +/- 0.10, pK(6) = 12.99 +/- 0.11 (by spectrophotometry). They were determined at I = 0.4 and at 25 degrees.

Dissociation constants of carboxymethyloxysuccinic acid

Talanta, 1974
The dissociation constants of carboxymethyloxysuccinic acid (CMOS) have been measured at 25 degrees and an ionic strength of 0.1M in sodium perchlorate. The values found were: pK(1) = 2.52, pK(2) = 3.77 and pK(3) = 5.00. CMOS is thus seen to be rather stronger than its isomer citric acid.

Dissociation constants of arsenazo III

Talanta, 1986
Commercial samples of Arsenazo III were found to be appreciably impure even after purification as the barium salt. Chromatography on silica gel followed by crystallization yielded a pure sample of the ethanol solvate of the free acid. The dissociation constants of the acid were determined potentiometrically at 25 degrees and I = 0.1 (NaClO(4)).
