What are some physical properities to distinguish water and rubbing alcohol?

Answer 1

Hi

Two Physical Properties which can be used are

1)Boiling point difference

Water boils at 100C

Ethanol boils at 78.30C

2)Ethanol is lighter than water because its density is less than water.

Density of ethanol =0.789g/ml

Density of water is 1.00g/ml

he physical properties of substances are their boiling point,melting point,density ,solubility etc.

Answer 2

-Smell the two, alcohols often have a distinct odor, while water does not.

-Alcohol's boiling point is lower than waters.

-Alcohol's freezing point is very low, it's used as an antifreeze. Cool the two, maybe even put them in the freezer and the one that freezes is pure water.

-Alcohols are also very flammable, take a match to a small quantity of both and the most flammable on is an alcohol.

-Alcohol's specific heat is different from water's. Water's is about 4.184J/gC and ethyl alcohol's is 2.460J/gC, meaning that water will heat up slower than alcohol. using a very, very light fire/heater, warm the two liquids, the one that warms up the fastest is the alcohol.

These are but some.

Answer 3

easiest is using some universal PH paper, water will be less acidic. Otherwise i guess you can do a titration with a suitable indicator and some base.

----

density, refractive index, color

Answer 4

A physical property of isopropyl alcohol is that it is flammable at room temperature. A chemical property of isopropyl alcohol is it is oxidized by the liver into acetone.

Answer 5

The physical property of rubbing alcohol are:

• liquid
• something that I can't think of
• another thing that I can't think of

Answer 6

Water has a boiling point of 100°C, whereas rubbing alcohol (usually isopropyl alcohol) has a boiling point of 82°C.

Answer 7

Some physical properties to distinguish water and rubbing alcohol are: density, color, refractive index, freezing point, boiling point.
