Solubility is defined as the ability of a substance to dissolve in a solvent. Solubilities of ionic compounds vary depending on the constituent cation and anion. The solubility rules predict the ability of an ionic compound or a salt in an aqueous sol...
What is the parts per million (ppm) concentration of the {eq}Mg^{2+}(aq) {/eq} cation in a 0.0250 M {eq}MgCl_2(aq) {/eq} solution? Magnesium Chloride: When magnesium chloride is dissolved in acetone, it becomes soluble. Magnesium chloride has...
This apparent reversal of cation/anion selectivity is intriguing, and it suggests a key role of the pore passageway in ion permeation across the membrane. Channel gating. The well-defined series of water molecules through each protomer of the high-resolution type 2a SaTRIC structure (Figs 3 ...
This work aims to study the effect of NaCl, KCl, NH4Cl, CaCl2 or MgCl2 on the solubility of two glycine derivatives, glycylglycine (a.k.a. diglycine) and N-acetylglycine, and to understand the nature of the interactions present on these systems. Experimentally, upon increasing the ...

However, the interfacial nanogaps that were present in the functional layer of the decorated membrane cannot be fully avoided [18]. ZIF-8 has a small aperture with a size of 3.4 Å and a comparatively large cavity with a size of 11.6 Å [19]. The small aperture of ZIF-8 can serve...
