When titrated by a strong base such as 0.1 M NaOH solution, a solution of citric acid traverses a buffer region during which the pH of the solution climbs gradually then more steeply. From about one ...

A well-established technique, acid-base titration is an analytical method used to determine the concentration of an unknown acid or base. In practice, it involves adding a solution of known strength ...

Part 1 of this article was published in Chem 13 News in November 2014. This second part presents three titration exercises of increasing sophistication, suitable for students with some titration ...

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 ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. Acid–base titrations are widely used in chemical analysis, and ...

Herein, we report on a reagentless electroanalytical methodology for automatized acid-base titrations of water samples that are confined into very thin spatial domains. The concept is based on the ...

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 ...

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 ...

Amount and properties of roots surface charge are important for nutrient uptake and balance in plants. Roots surface charge markedly varies at different rizosphere conditions (particularly pH and ...
