A water bath must be used while heating ethanol and acetone because the temperatures at which they can be heated might break the container they are heated in. Some metals are also heated this way.

Which has a higher surface tension ethanol or acetone?
acetone. It has a surface tension of 23.70 at 20 degrees celsius while ethanol has a surface tension of 22.75 at 20 degrees celsius
Is the vapor pressure of water and acetone different?
The three liquids have different densities. Water has a density of 1g/mL. Acetone has a density of 0.791g/mL. Ethanol has the density of 0.789g/mL. Also, ethanol has the strong smell that resembles one of nail polish remover. Ethanol is used in alcohol. Acetone is practically a type of acid.
How do you distinguish between hexane and ethanol?
With Ethanol and Distilled water.. IT is suppose to turn cloudy so fats are present.
What will boil first water or alcohol?
I assume that by "boils faster" you really mean "boils at a lower temperature", and that by "alcohol" you mean "ethanol". Ethanol has a lower boiling temperature than water at standard pressure. However, a mixture of ethanol and water boils lower than either by themselves do. This is called an "azeotrope" and it happens for ethanol/water mixtures at about 95% ethanol, which is why it's essentially impossible to get ethanol to more than 190 proof by distillation alone.
What are two tests distinguish between ethanol and phenol?
with water ethanol is soluble while methane is in soluble

Is ethanol the same as salt water?
No, it is not. Salt water is NaCl and H2O, while ethanol is C2H5OH.

Will ethanol float or sink?
Ethanol is less dense than water so it will initially float on a water surface. Given that ethanol is totally miscible with water, an ethanol layer on top of a water layer will diffuse into the water while the water will diffuse into the ethanol until a single uniform composition solution of alcohol and water is achieved.
What effect does adding water have on the boiling point of ethanol?
The pure ethanol has the boiling point 78.5 celsius while water has 100 celsius so when water is added to ethanol its boiling point becomes increased.
How do you convert acetic acid to acetone?
You can do this very carefully with distillation. The boiling points of these two are between 25 and 44 Celsius difference, depending on the ratio of acetone and water. Using distillation, you can boil the mixture gently to around a stable 44 Celsius, which will evaporate the acetone and leave the water. The water will not evaporate unless the temperature reaches 100 Celsius.
What will happen to the water while heating?
evaporation
Does water affect the heat of combustion of ethanol?
There are two angles to this question: 1. If your ethanol is contaminated with water it will reduced the amount of useful heat generated since the water will boil off while the ethanol is burning. 2. The water generated as a result of combustion is included as a term in the calculation of heat of combustion.
what is the outcome of tollens reagent reacting with methanal, ethanol and propanone?
The outcome of the Tollens reagent reacting with methanal (formaldehyde), ethanol (ethyl alcohol), and propanone (acetone) is the formation of metallic silver (Ag) in the case of methanal, while ethanol and propanone do not show a significant reaction with Tollens reagent. Tollens reagent is used as a chemical test to distinguish between aldehydes and ketones, where aldehydes react to produce a silver mirror, while ketones do not react.
