Acid-base homeostasis operates to maintain extracellular arterial pH between 7.35 and 7.45, and intracellular pH between 7.0 and 7.3 in order to provide an optimal milieu for enzymatic and metabolic processes. Since pH is equal to –log [H+], with the concentration of hydrogen ions in Eq/L...

Here, we show the design and synthesis of a Cu(II) metal-organic framework (FJI-H14) with a high density of active sites, which displays unusual acid and base stability and high volumetric uptake (171 cm3 cm−3) of CO2 under ambient conditions (298 K, 1 atm), making it a...
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
Acid-Base Equilibrium Constants The pH scale measures the hydrogen ion concentration in a solution, indicating whether it is acidic, neutral, or basic. The terms pKa and pKb represent the negative logarithms of the acid and base dissociation constants, Ka and Kb, respectively. They help determine...
