It can be noticed that all curves have the same S-Shape, characteristic of the irradiation response of a pH indicator in an acid-base titration
with different sensitivities.
The degree of deacetylation of chitosan samples was determined by acid-base titration
Table 1: Traditional textbook approach to calculations for an acid-base titration
, corresponding to the first half of example 1.
Calcium was defined by method of flame photometry (Pokrovskiy, 1969); inorganic phosphorus--by colorimetrical method (Pokrovskiy, 1969); magnesium--by complexometric method; urine PH index, buffer base shift [BE], standard buffer system [SB], and ammonia in urine were defined using Conway method (Pokrovskiy, 1969); acid-base titration
and pH were defined by potentiometric titration (Toderov, 1966), content of urine acid--by spectrophotometer (Menshikov, 1987), urine oxalate (Sivarinovskiy, 1969).
Laboratory modules were written for gas laws, thermodynamics, and acid-base titration
The acid-base titration
curves for styrene-maleic anhydride polymers gave the first indications that it should be possible to form amic acid derivatives of these resins.
Another interesting interpretation of the graph came from the student in User Focus Group 2, who interpreted the graph as representing a reaction of an acid and an externally added base, such as the situation for an acid-base titration
The proper choice of indicators was a difficult problem that could be resolved only with a clear understanding of the significance of acid-base titration
curves and the effect upon them of various buffers.
The accumulative concentration of PTA was determined by standard acid-base titration
Metrohm also has a potentiometric acid-base titration
technique for determining the acid number in biodiesel.
is a very mature analytical technique but recent developments in data analysis and equipment warrant additional study of this common laboratory practice.
