An acid-base indicator is a substance that changes color as the pH of the solution changes. Indicators work because they are weak acids which when in solution, exist in equilibrium with their ...

This lab includes a demonstration of the proper use of a burette system for titrations; including a detailed description, instructional video, and opportunity for students to collect data to ...

I’m sure many of you reading this can remember your first acid-base titrations in chemistry class—the thrill of watching the pH indicator change color, and the fear of opening the stopper too much and ...

The new application notes are: • AN-H-124 Determination of sodium for the manufacture of margarine • AN-H-125 Determination of sodium in soy milk Thermometric titration is faster than potentiometry ...

The process of carrying out a titration allows us to accurately measure the volumes of an acid and an alkali required for neutralisation. An indicator will be used to determine the exact volume ...

Metal-organic compounds are commonly used in organic chemistry, for example as Grignard reagents or as strong bases (e.g., butyl lithium compounds). The knowledge of the exact content of reactive ...

Limnology and Oceanography (L&O;) publishes research articles, reviews, and comments about all aspects of limnology and oceanography. The journal’s unifying theme is the understanding of aquatic ...

THE structure of polyadenylic acid can be expected to have some influence on the availability of polar groups, such as the primary amino-group of the adenine base, for binding of hydrogen ions.
