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 ...

(1) Germination and early seedling growth of Pinus contorta and Picea glauca were examined, using distilled water (pH 6·3), eight acidic buffer solutions (pH 2·2), and eight alkaline buffer solutions ...

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 ...
