How do you calculate activity and activity coefficient? [FAQ!]

Web10 apr. 2024 · According to the tests, 3 and 4 show higher sensitivity and selectivity towards Fe3+ ions, but 2 reveals lower sensitivity and selectivity towards Fe3+ ions. Moreover, 1–4 display higher sensitivity and selectivity towards Cr2O72− anions. Notably, 3 is rare Gd-MOF sensor to Fe3+ ions, and 4 is rare Y-MOF sensor to Cr2O72− anions. WebACTIVITY In concentrated solutions, ions interact electrostatically with each other (surrounded by a cloud of opposite charge) so the stoichiometric coefficients do not …

WebThe activity coefficients decrease steadily when the ionic strength I rises. However, both the Davies and the Truesdell-Jones equations contain an additive term that causes a re-increase when I approaches 1 mol/L – see … WebGCSE worksheet on explaining properties of ionic substances. Students build a model of an ionic lattice using plasticine and straws. They then use this model to explain a variety of physical properties of sodium chloride including high melting point, conductivity and brittleness. ( PDF) Tests for ions
