This presentation will focus on revising some of the key topics in A-Level acid-base chemistry, e.g. definitions, calculating pH, acid-base titrations, titration curves and buffer solutions as ...

So, if the concentration of hydrogen ions exceeds 1 mole per liter, as in a 12 M hydrochloric acid solution, the calculated ...

Question: What’s the difference between soil pH and buffer pH? My soil has a pH of 5.1 and a buffer pH of 6.7. Answer: Soil pH is the measure of active acidity. Active acidity is soil solution ...

In this study, stimulus-sensitive gel particles with DNA–dye complexes were prepared. This composite has potential use in optical micro-sensors because it can change its dye concentration in response ...
