Why aqueous solution prefer for dyeing?
since the availability of water is more and is cheap compared to other organic solvent.
Why caffeine soluble in chloroform?
Caffeine is a polar molecule thus it has hydrophobic portions, and dichloromethane is s polar organic solvent which is fairly good at dissolving most organic molecules. In water caffeine dissolves for the most part via formation of hydrogen bonds where atoms with free electron pairs are involved, and the solubility of caffeine in water in 2.2mg/mL at 25 C, 180 mg/mL at 80 C, and 670 mg/mL at 100 C. where caffeine is not all soluble in water at room temperatureWhen caffeine is brought in close contact with dichloromethane most of the caffeine migrates into the organic layer.
Why did the caffeine leave the water and move into the dichloromethane?
Dichloromethane is a water-immiscible solvent that works well, because caffeine is highly soluble in it
Does fingernail polish remover contain water?
No, the solvent is organic.
When would you prefer to use an air cooled condenser with no water running through it during organic chemistry distillation?
Air condenser can be used when the boiling point of the solvent is very high, as the air temperature will to sufficient to condense the solvent vapour. Water condenser is generally used when the solvent boiling temperature is less e.g., water, ethanol etc.
Is water an organic or inorganic solvent?
It's an inorganic compound.
How do youget caffeine out of coffee?
Decaffeination is the process through which caffeine is removed from whole coffee beans. Water Decaffeination is the most popularly employed method to decaffeinate coffee. Water method simply uses water to extract caffeine from coffee without using any chemical solvents. One of the most famous water decaffeination methods is called Swiss water decaffeination. Water decaffeination is a non-toxic process that does not change the flavour or aroma of the coffee beans. Another method uses carbon dioxide to remove caffeine. In this process, the combination of high temperature and pressure enables carbon dioxide to become a solvent. The oldest method man has used to extract caffeine from coffee involves soaking the coffee beans in a caffeine-absorbing solvent. The caffeine soaks into the solvent and the solvent containing the caffeine is separated from the beans. The process of soaking and extraction is repeated over and over until the caffeine level reaches the desired level
What is the name of the element that is called universal solvent?
It's not an element, but a compound that's called the universal solvent, and that compound is water. The strong polar nature of water means that it dissolves many polar covalent and ionic substances.
Why is KNO3 and CCL4 not miscible?
KNO3 is potassium nitrate. It is an IONIC compound which dissolved in water. CCl4 is tetrachloromethane, it is a COVALENT compound, which is misxible in organic solvents.
Is water known as the universal solvent?
Water dissolves thousands of compounds (organic and inorganic) no one other solvent dissolves such huge no of compounds so it is known as universal solvent.
Which type of organic compound contradicts water's reputation as a universal solvent?
Gasoline and anything with higher hydrocarbons contradicts water's reputation as a universal solvent.
Are kerosene and oil soluble?
No. Kerosene is an organic compound. and water is a non-organic compound. (kerosene : non-polar Water : polar). As water is a polar solvent kerosene is not soluble in it. but kerosene is soluble in ethyl alcohol which is a non-polar solvent.
