Super hygroscopic polymer films composed of biomass and hygroscopic salts are able to condense moisture from atmospheric humidity. [16] By implementing rapid sorption-desorption kinetics and operating 14–24 cycles per day, this technique produced an equivalent water yield of 5.8–13.3 L kg −1 of sustainable raw materials, demonstrating the ...
Gypsum (CaSO 4.2H 2 O) is a hydrate solid that, in a sufficiently dry environment, will give up its water to the gas phase and form anhydrite (CaSO 4). Copper(II) sulfate (bluestone) (CuSO 4 .5H 2 O) is a blue crystalline solid that when exposed to air, slowly loses water of crystallization from its surface to form a white layer of anhydrous ...
Potassium carbonate is the inorganic compound with the formula K 2 C O 3. It is a white salt , which is soluble in water and forms a strongly alkaline solution. It is deliquescent , often appearing as a damp or wet solid .
2 SiO 3, which is the main component of commercial sodium silicate solutions. It is an ionic compound consisting of sodium cations Na + and the polymeric metasilicate anions [– SiO 2− 3 –] n. It is a colorless crystalline hygroscopic and deliquescent solid, soluble in water (giving an alkaline solution) but not in alcohols. [1]
This colorless deliquescent salt is one of the main sources of the thiocyanate anion. As such, it is used as a precursor for the synthesis of pharmaceuticals and other specialty chemicals. [2] Thiocyanate salts are typically prepared by the reaction of cyanide with elemental sulfur: 8 NaCN + S 8 → 8 NaSCN
Potassium citrate (also known as tripotassium citrate) is a potassium salt of citric acid with the molecular formula K 3 C 6 H 5 O 7. It is a white, hygroscopic crystalline powder. It is odorless with a saline taste. It contains 38.28% potassium by mass. In the monohydrate form, it is highly hygroscopic and deliquescent.
