Provisional pH values for certain standard buffer solutions

PROVISIONAL pH VALUES FOR CERTAIN STANDARD BUFFER SOLUTIONS

For use in the calibration of electrometric pH assemblies, 17 standard buffer solutions have been investigated, and pH values at 20°, 25°. and 30° C have been assigned to them. The pH values of these solutions range from 2.27 to 11.68 and are considered accurate to ± 0.02 pH unit. Hydrogensilver-chloride cells without liquid junctions were used for establishing the precise pH values of the buff...

The Kinetics of Saponification of Iodoacetic Acid by Sodium Hydroxide and by Certain Alkaline Buffer Solutions

1. The rate of the saponification of iodoacetic acid in sodium hydroxide and alkaline buffer solutions yielding glycollic acid was measured by means of Heyrovský's polarographic method. 2. From the bimolecular velocity constants, increasing with the ionic strength of the solution, the Brönsted factor, F, which characterizes the primary salt effect, was calculated. 3. In the borate buffer soluti...

Semi-mechanistic partial buffer approach to modeling pH, the buffer properties, and the distribution of ionic species in complex solutions.

In many biological science and food processing applications, it is very important to control or modify pH. However, the complex, unknown composition of biological media and foods often limits the utility of purely theoretical approaches to modeling pH and calculating the distributions of ionizable species. This paper provides general formulas and efficient algorithms for predicting the pH, titr...
