Use of Argyreia cuneata Flower Extract as a Natural Indicator in Acid Base Titration

Dahalia Flower Sap a Natural Resource as Indicator in Acidimetry and Alkalimetry

Dahlia pinnata is a species of the genus dahlia, belonging to the family Asteraceae. The present study reported the use of dahlia pinnata flower extract as an acid base indicator in different types of acid base titrations. The equivalence point obtained by the flower extract coincided with the equivalence point obtained by standard indicators. The results obtained by the flower extract matched ...

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...

Use of Moringa oleifera Flower Pod Extract as Natural Preservative and Development of SCAR Marker for Its DNA Based Identification

The use of Moringa oleifera as natural food preservative has been evaluated in the present study. In addition, for quality assurance, the study has also been focused on the shelf life of product to authenticate the identification of plant by development of DNA based marker. Among the different extracts prepared from flower pods of Moringa oleifera, methanol and aqueous extract exhibited high an...

The Use of Salicylaldehyde Phenylhydrazone as an Indicator for the Titration of Organometallic Reagents.

Acid-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, ...
