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 ...

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.

Estimates show that without the usage of fertilizers, around half of the world’s population could not be supported 1. Thus, in the modern world, agriculture at significant scale without fertilizers is ...

A simple, alkalimetric method is described that can be used to determine bicarbonate and total volatile fatty acid concentrations in anaerobic digesters by a two-stage sequential titration. The new ...

The study of acid-base regulation may be seen as a continuation of research focused on physiological homeostasis, a concept first formulated early in the nineteenth century and spelled out by Bernard.

Terpenoid cyclases catalyze the most complex reactions in biology, in that more than half of the substrate carbon atoms often undergo changes in bonding during the course of a multistep cyclization ...

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 ...
