The assessment of acid-base disturbance in man by the use of carbon dioxide titration curves.
1. Carbon dioxide titration curves were determined in vivo in dog and man at various degrees of acute non-respiratory acidaemia and alkalaemia. 2. The slope of the CO2 titration curve (delta log Pco2/delta pH) was found to increase with the severity of the acute non-respiratory alkalaemia the slope (delta log Pco2/delta pH) tended towards unity. 3. A simple scheme based on the CO2 titration cur...
متن کاملAcid-Base Titration Curves in an Integrated Computer Learning Environment
The topic of acid-base reactions is a regular component of many chemistry curricula that requires integrated understanding of various areas of introductory chemistry. Many students have considerable difficulties understanding the concepts and processes involved. It has been suggested and confirmed by research that students may be benefit from computer-supported activities such as data logging, ...
متن کاملA Student-Designed Potentiometric Titration: Quantitative Determination of Iron(II) by Caro's Acid Titration
Oxidation–reduction titrations and potentiometric methods provide a convenient experimental means to quantitatively determine compositions of unknown mixtures containing oxidizable/reducible species. Over the past decade, numerous titration methods have appeared in this Journal (1–6) and in standard laboratory manuals (7–10) involving common titrants such as potassium dichromate, iodine, potass...
متن کاملStants from Acid Titration Data
It has been shown earlier that the titration curves of wool and other proteins obtained with different strong acids differ widely in position with respect to the pH coordinate. By assuming that these differences were due to combination of the protein with anions as well as with hydrogen ions, it was possible to calculate from the pH of the midpoint of each curve numerical values of tbe affinity...
متن کاملNon Aqueous Titration for the Determination of Azelaic Acid: Introduction and Method Validation
Alpha-hydroxylic acids are widely used in the treatment and control of skin disorders. Azelaic acid is a naturally occuring Alpha-hydroxy acid that can be formed endogenously from long-chain dicardoxylic acids, metabolism of oleic acid or omega oxidation of mono carboxylic acids. It shows bacteriostatic and bactericidal activities against aerobic and anaerobic micro-organisms present on acne-be...
