(ii) Non-polar particles can dissolve in non-polar solvents (eg. C6H12, C6H6). (4) Ionic compounds have high solubility in water ? Ions are easy to form bonds with water molecules (they are polar). ? Lattice structure is broken, ions fixed in the lattice structure become free moving ...
1. Why is NaCl soluble in water? (solubility: 20 oC, 36.0 g/100 g water) Recall the guideline: the interaction between the water molecules and Na+ and Cl- is bigger than the ionic bonding. 2. Why is CaI2 (solubility: 20 oC, 67.6 g/100 g water) less soluble than CaCl2 (solubili...
Room-temperature ionic liquids are molten electrolytes that exhibit interesting solvent properties including nonvolatility and nonflammability, high viscosity, high thermal stability, and high solubility of a broad range of organic and inorganic compounds [65]. These attractive properties allow the high-...
This strategy increased the solubility of the lithium-ion salts significantly, and at the same time allowed successful cycling of complete LIB cells with adapted electrode materials for over 500 charge/discharge cycles. The same research group also altered the activity of the water molecules in the...
Herein, the solubility of 6-methyl-2-thiouracil – a common antithyroid drug, with low solubility in water and common organic solvents – was studied by employing six different imidazolium-based ionic liquids with variable anions. We demonstrate facile, regiospecific S -alkylation of 2-thiouracil ...
Ionic Liquids are a promising alternative to water electrolytes for the electrodeposition of metals. These solvents have a much larger electrochemical window than water that expands the potential of electrodeposition. However, mass transport in Ionic Liquids is slow. The slow mass transport dramatically ...

(dry) ionic liquids6,7, can provide a platform for high enzyme solubility (>50% by mass) with a significant increase in thermal stability. Nevertheless, the activity of some enzymes is improved in ionic liquid–water mixtures, most notably these include lipase-catalysed esterification or ...
