What volume of ethyl alcohol and water must be mixed together to prepare 250 ml?
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.
What volume of ethyl alcohol and water must?
Now for calculating the volume of water we will subtract the volume of ethyl alcohol from the volume of the solution. So, for preparing [250ml]of [60% ] by volume solution of alcohol in water, [150ml] of ethyl alcohol is required and [100ml] of water is required.
What happens to the total volume when ethanol and water are mixed?
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. … As the molecules pack tighter together, the solution becomes more dense.
When ethyl alcohol and water mixed together then solution formed is?
What will be the nature of the solution when ethyl alcohol and water are mixed ? The solution will show po9sitive deviation from Raoult’s law.
How do you make 95% alcohol to 75?
To replace 1 liter of 95% alcohol we have to use 1.26 liters of 75% alcohol. We need more 75% alcohol because water was added to 95% alcohol to bring it down to make the 75% version.
How much water should be mixed with 25 ml of alcohol so as to obtain 12% alcohol solution?
How much water should be mixed with 12 mL of alcohol so as to obtain 12% alcohol solution? Hence, 88 ml of water will be added to 12 ml of alcohol in order to prepare a concentration 12%.
Why does the volume decrease when you mix water and alcohol?
When the molecules of isopropyl alcohol or methanol slip between the water molecules, the volume decreases as the molecules in the mixed liquid become more compacted.
Is it good to mix alcohol with water?
Alternating alcoholic beverages with water or juice will keep you hydrated and spread out the total amount of alcohol you drink. Finally, be aware that drinks in bars and restaurants may contain more alcohol than you think.
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.
When 50ml of ethanol is mixed with 50ml of water?
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.
Are alcohol and water miscible or immiscible?
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.
