What happens when you mix alcohol and water together?

When you mix the rubbing alcohol with water, the latter’s molecules make hydrogen bonds with the water molecules. The alcohol dissolves in the water to form a homogenous solution, so you cannot distinguish the alcohol and the water anymore.

Is volume conserved when two liquids are mixed?

When one volume of liquid is mixed with another volume of liquid that is less dense than the first, the total volume of the two liquids will not be the sum of the two individual liquids. The molecules of one liquid can fill in the volume between the molecules of another.

Why does a cup of alcohol and a cup of water not equal two cups of liquid?

Why? Rubbing alcohol molecules filled the water molecules. The shape of the alcohol molecules let them slide right in between the water molecules. Another quick experiment would be used to prove that these “invisible” molecules are always moving.

Why is the total volume of water and alcohol less?

When water and ethyl alcohol mix, several forces come into play. First, between the water and ethyl alcohol is strong hydrogen bonding that draws the different molecules close together. The 2 different molecules pack closer together than in pure solution, resulting in a reduction of volume.

What happens to the total volume when ethanol is added to water?

But, if you mix 50 mL of water and 50 mL of ethanol you get approximately 96 mL of liquid, not 100 mL. Ethanol molecules are smaller than water molecules, so when the two liquids are mixed together the ethanol falls between the spaces left by the water.

Why does the volume decrease when alcohol and water are mixed?

When you mix alcohol and water is the volume conserved?

Are the mass and volume conserved? If ethyl alcohol is mixed with distilled water, the mass is conserved, however, volume is not. The volume will decrease in this reaction as a result of ethyl alcohol disrupting the water molecule’s structures and also because of the tighter packing of molecules in the new mixture. 2.

Why is alcohol less dense than water?

Although alcohol also contains oxygen atoms, its molecules are not able to pack together as tightly as water molecules, and so it is less dense than water.

When equal volumes of ethanol and water are mixed?

On mixing equal volumes of water and Ethanol there is positive deviation is appeared or formed.

Why does volume decrease when water and ethanol are mixed?

What happens to volume when iso-propyl alcohol or methanol is mixed with water?

When the molecules of ISO-propyl alcohol or methanol slip between the water molecules, the volume decreases as the molecules in the mixed liquid become more compacted. we know that mass = density x volume , the mass is conserved , but the density is increased as in the above case accordingly the volume decreases using the equation above

What happens when you mix alcohol with alcohol?

Alcohol absorbs water, so that the volume of the two when mixed is less than the combined separate volumes of each. The new concentration is correct even while the total volume is slightly less than expected by simply adding the numbers.

Why does ethyl alcohol have less volume than water?

Second, open spaces in the liquid are much less likely because the ethyl alcohol interferes with any temporary open structures that are similar to those of solid water. The 2 different molecules pack closer together than in pure solution, resulting in a reduction of volume.

Why does adding rubbing alcohol to water increase its volume?

Adding something like rubbing alcohol to another liquid will normally increase the volume simply because you have added more matter. However, if you are referring to a situation like having 100 mL of water vs 90 mL water with 10 mL rubbing alcohol, there is a different answer, because those two volumes would be slightly different.
