Salting out isopropyl alcohol increases the potency of the alcohol by using salt to draw the water out of the alcohol. The salt dissolves in the water, but is insoluble in isopropyl alcohol, making the water heavier and separate to the bottom while the isopropyl alcohol floats on the top.
The intercalation of VOPO<sub>4</sub> with the mixtures of alcohols (ethanol and 1-butanol, methanol and ethanol, methanol and 1-propanol, methanol and 1-butanol) have been studied.
Most sources on the solubility of various sulfite and sulfate salts in ethanol indicate that solubility is below 100 ppm. However, there is experimental evidence that sodium sulfate solubility in ethanol is particularly low, i.e., no more than 0.3 ppm, and likely much lower. A
Apr 28, 2009 · The purpose of this lab is to determine the relative solubility of the following solvents: water, rubbing alcohol, vegetable oil. You will have the following solutes to conduct this experiment: sugar, salt, and cornstarch. Materials: Below is a list of materials for the lab.
SOLUBILITY: 1-butanol [C 4 H 9 OH]: 0,005 (20°), 1-hexanol [C 6 H 14 O]: 0,001 (20°) 1-pentanol [CH 3 CH 2 CH 2 CH 2 CH 2 OH]: 0,002 (20°) 2-butanol [CH 3 CH(OH)CH 2 CH 3]: 0,00047 (25°), 2-ethylhexanol [C 8 H 18 O]: 0,0001 (20°) ammonia liquid [NH 3]: 4,2 (-30°), 12,9 (0°) acetone [(CH 3) 2 CO]: 0,000032 (18°) benzalcohol [C 6 H 5 CH 2 OH]: 0,017 (20°) water [H 2 O]: 35,7 (0°), 35,9 ...
Deliquescent salts are usually soluble in alcohol, potassium carbonate being a notable exception to this rule, while salts which effloresce are mostly insoluble. Sulphur and phosphorus are dissolved to a small extent, and iodine freely.
