In most cases, the substance to be extracted, which may be a solid, a liquid or a gas, is dissolved in a liquid, along with other substances, and a liquid solvent is used for the extraction — this is sometimes called liquid-liquid extraction. The technique may also be applied to ...
What is fractional distillation? Write its definition and process. Fractional Distillation: There are a number of types of distillation. The most common one is the simple distillation and the fractional distillation. This is marked with liquid conversion to vapor conversion. Answer and Explanation: ...
Liquid–liquid extraction (LLE) is based on the principle that a solute or an analyte can distribute itself in a certain ratio between two immiscible solvents, usually water (aqueous phase) and organic solvent (organic phase). What is age hardening? Age hardening, also known as precipitation ha...

作者: Johnson,Keith,E. 展开 摘要: The article presents information on ionic liquids. The term ionic liquids was introduced to cover systems below 100°C. The properties of a modern ionic liquid include low vapor pressures and moderate specific conductivities. The molarity of the liquid is impor...
What does an ionic liquid surface really look like? Unprecedented details from molecular simulations We present the first intrinsic analysis of the surface of the [bmim][PF6] room-temperature ionic liquid. Our detailed analysis reveals unprecedented detail......
From drug development and DNA sequencing to high throughput PCR testing, automated liquid handling has revolutionised the way modern laboratories operate. Click to read more...
One liter of 70% alcohol is needed. How much 90% alcohol is required to make the 70% solution? How many milliliters of water would you need to make a 10-2 dilution using 10ml of a culture? Which of the following glassware should be used for liquid-liquid extraction? Buchner funnel,...
the water that is trapped inside hydrated crystals may still require higher temperatures to break free and evaporate. a lot of energy is absorbed by the feedstock at this point in order to convert all the liquid water into water vapour. at this temperature point, the sugars, fats, and waxes...
