If you mix 50 ml of water with 50 ml of ethanol, the total volume actual equals less than 100 ml. The reason the mixture does not add up to 100 ml is
because the molecules that make up ethanol are smaller than the molecules that make up water
. So, the ethanol molecules cram themselves between the water molecules.
What happens when 50 mL of water and 50 mL of alcohol are mixed?
If you add 50 mL of water to 50 mL of water you get 100 mL of water. Similarly, if you add 50 mL of ethanol (alcohol) to 50 mL of ethanol you get 100 mL of ethanol. … 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
.
When 50 mL of liquid A is mixed with 50ml of liquid B total volume of the solution after mixing is found to be less than 100ml What type of non ideal solution is formed?
adding 50 mL of water to 50 mL of water will result in a total volume of 100 mL, and adding 75 mL of 100% ethanol to 75 mL of 100% ethanol will result in a total volume of 150 mL.
What volume will you have when you add 250 mL water with 250 mL alcohol?
Is the volume additive? The Law of Conservation of Mass dictates that the mass is conserved, but is there a Law of Conservation of Volume? No, if you mix 250 mL of water with 250 mL of ethyl alcohol, only
about 480 mL
of solution results.
What is the volume of alcohol and water mixture?
Explanation: When 50 milliliters of water are added to 50 milliliters of alcohol, the volume of the two mixed together is only about
96 or 97 milliliters
. When mixed together, the combined molecules fit together better than when they are alone, so they take up less space. Water and ethanol mix to form a solution.
What happens when alcohol and water mix?
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?
Concept: The total mass of substances does not change during a chemical reaction. 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.
What type of non ideal solution is formed give its two characteristics?
Characteristics of Non-ideal Solutions
Non-ideal solutions depict characteristics as follows: The
solute-solute and solvent-solvent interaction
is different from that of solute-solvent interaction.
What is negative deviation from Raoult law?
If the vapor pressure of a mixture is lower than expected from Raoult’s law
, there is said to be a negative deviation. Negative deviations from Raoult’s law arise when the forces between the particles in the mixture are stronger than the mean of the forces between the particles in the pure liquids.
Which of the following will form an ideal solution?
Solution:
C6H6 and C6H5CH3
will form an ideal solution over the entire range of composition.
What volume of ethyl alcohol and water must be mixed together to prepare 250 ml of 60 by volume?
HERE IS THE ANSWER. 60% by volume of alcohol solution means,each 100 ml of solution will have 60 ml ethyl alcohol. hence in a 250ml solution of 60% by volume of alchohol and water,alcohol should be
150 ml
and water should be 100 ml.
When you mix alcohol and water is the volume conserved?
When you mix alcohol and water,
the volume is not conserved
. This is due to the different packing in of the molecules and different sizes of the alcohol molecules and water molecules. Molecules of (ethyl) alcohol pack together closely and find nooks and crannies to squeeze into when mixed with water.
How many ml of water must be added to 300 ml of 70% alcohol solution to make a 40% alcohol solution?
c2=40%;V2=? Thus, you would add
225 mL
of water to 300 mL of 70 % alcohol, and you would get 525 mL of 40 % alcohol.
Are alcohol and water miscible or immiscible?
Solution: Alcohol and water form a miscible solution because alcohol is soluble in water and oil are not soluble in water hence it forms an
immiscible solution
.
Why is the volume of the water and alcohol mixture less than 100ml?
Unlock
The reason the mixture does not add up to 100 ml is because
the molecules that make up ethanol are smaller than the molecules that make up water
. So, the ethanol molecules cram themselves between the water molecules. As a result, the volume is less than expected. The volume adds up to approximately 96 ml.
Why is mixing ethanol and water exothermic?
Upon dilution in water, the alcohol is inserted in a weak chain and renders the adjacent water-bond strong. As a consequence,
the dilution of an alcohol in water is always exothermic
. The dilution of water in an alcohol causes stabilisation of the H-bonds but has a negative effect on the non-specific cohesion.
