Why does the water freeze when a beaker of ether is placed over the water?
Because ether is much more volatile than water and evaporates extremely quickly. As ether evaporates very quickly its average kinetic energy is lowered as molecules of ether escape. Following on, the 2nd law of Thermodynamics (I think) states that thermal energy is lost to cooler things so the water cools down extremely quickly as it looses heat to the evaporating ether which is also loosing heat in evaporation. Once the water reaches 0 degrees C it freezes.
Is picric acid more soluble in water or ether?
In ether. However the difference is not so significant. The solubility of the commercially sold sample (%100 pure) in water is reported as 1g/65 ml. and in ether as 1g/78 ml. They account for 15.4 g/L water and 12.8 g/L ether. You can check out such properties of materials here:
Why is dimethyl ether soluble in water but pentane is not?
Dimethyl ether is soluble in water because it is polar, with a dipole moment allowing it to form hydrogen bonds with water molecules. Pentane is nonpolar and lacks the ability to form significant interactions with water molecules, making it insoluble in water.
Why do people have to be very careful when using ether?
People need to be careful when using ether because it is highly flammable and can easily ignite when exposed to heat or open flames. Inhaling ether vapor can also cause dizziness, nausea, and headaches. Additionally, ether can be harmful if it comes into contact with the skin or eyes.
why is it that sodium chloride is insoluble in ether?
Ether has a lower dielectric constant than water. Therefore, the energy required to separate the cations from the anions in ether is greater than in water. The entropy gain that could result from converting solid salt to a solution is therefore not great enough to overcome the attractions between the ions in ether, but it is great enough in water.
Which causes more cooling ether or water?
Assume question is about evaporative cooling rate Ether had vapour pressure of around 0.7 ATM it would be readily evaporate in air. The ether would be a lot colder than water and cause higher cooling rate. However, if the matter talk about conduction cooling or cooling per unit mass it might be different answer from above.

Why does salt soluble in water not in ether?
Water is a polar liquid; ether is not.
Solubility of pb with lipids?
The lipid glycerol is soluble in both water and ether. Olive oil is soluble in ether, but not water. A solid lipid is insoluble in water, methanol, and ether.
Is water denser than ether?
Ether is a gas and so the molecules are more spread out, making it less dense than water, whose molecules are so close together that water cannot be compressed.
Why does the ether precipitate when the alcoholic reaction mixture is poured into water?
The ether precipitates when the reaction mixture is poured into water because ether is less soluble in water compared to alcohol. Therefore, when the reaction mixture contains ether and alcohol is mixed with water, the ether separates out and forms a separate layer due to its low solubility in water.

How the vapour pressure of ether is greater than the vapour pressure of water?
Water molecules are held together by hydrogen bonds which are relatively strong. Ether molecules do not have such intermolecular forces holding molecules together. Therefore, it is easier for ether molecules to escape as a vapor, and this is why the vapor pressure of ether is greater than that of water.
Where does ether exert its effects on nerve activity?
Ether will impair the function of the nerves. It does not leave any permanent damage, however. Ether anesthetic may cause side effects such as nausea.
Are petroleum ether and water miscible?
No, petroleum ether and water are immiscible because they have different polarities. Petroleum ether is nonpolar, while water is polar, leading to a lack of attraction between the two substances and preventing them from mixing together.
Will ice float in ether?
No. It will sink because ice is denser than ether, and denser things sink to the bottom. Ice has a density of 0.9167 g/ml and ether has a density of 0.736 g/ml.
