litmus,litmus test- a coloring material (obtained from lichens) that turns red in acid solutions and blue in alkaline solutions; used as a very rough acid-base indicator bromophenol blue,bromphenol blue,tetrabromo-phenolsulfonephthalein- a dye used as an acid-base indicator ...
5. Is your blood acidic or alkaline?The pH of human blood is normal, ranging from 7.35 – 7.45. It suggests that blood is somewhat alkaline as well as basic by nature. For instance, the pH of human stomach acid ranges between 1.5 and 3.5. As a result, it is acidic....
A set of 543 ionizable commercial organic compounds with various acid/base functionalities and experimental octanol-water partitioning coefficients (log Kow) were obtained from the Canadian Domestic Substances List. Corresponding pH-dependent octanol-water distribution coefficients (log Dow) and air-water ...
A pH-sensitive detector for flow-through potentiometry based on a graphite/quinhydrone composite electrode was applied for flow-injection analysis (FIA) titrations. Hydrochloric acid and acetic acid were titrated by injection of samples into a sodium hydroxide carrier solution. System conditions were ...
We propose explicit and implicit approaches for the teaching of acid-base chemistry based on research into the history and nature of science (NoS). To supp
compared with the spectrum recorded in neutral solutions, pointing to the presence of two acid–base equilibria in the large pH range investigated. The spectrophotometric titrations followed at suitable monitoring wavelengths (430, 393, and 376 nm for DAQP, MIX, and QP, respectively) provided the...
