Why can't and alcohol thermometer be used to measure the boiling point of water?
Because the boiling point of alcohol is lower than the boiling point of water.
Why is fractional distillation is an appropriate technique to separate ethanol and water?
alcohol and water have different boiling point. i.e bp of alcohol is78C andwater is100C
Why is the boiling point of water unique?
Centigrade (or Celsius) is calculated using water, the freezing point being zero, the boiling point being 100.
What substance has a boiling point of 100 Celsius?
it is some type of alcohol did a distillation lab on it today
What is the effect of NaCl and CaCl2 on the boiling point of water?
The water with solved ions has greater boiling point. The dissolved salts increase the boiling point of water.
Why does lipids have to be placed in alcohol first before being placed water?
it has to be placed in alcohol first because lipids are soluble in alcohol but not in water.
Why can't and alcohol thermometer be used to measure the boiling point of water?
Because the boiling point of alcohol is lower than the boiling point of water.
Is there a difference in taste between steaming and boiling a live lobster?
When you steam the lobster, it is placed in a basket above a pot of boiling water. When you are boiling the lobster, it is placed directly into the boiling water.
How can you separate a mixture of alchohol and water?
Distillation! Water and alcohol have different boiling points; one is lower than the other. Heat the mixture up until it one of the two boils away. In the case of alcohol and water, alcohol has the lower boiling point. Heat the mixture to just above the boiling point of alcohol but below the boiling point of water and voila!- you've separated the mixture.
When cooking and salt is placed in the water and the water stops boiling give a reason for this phenomenon?
When the salt dissolves in the water it raises the water's boiling temperature, so it stops boiling.
What has a higher boiling point alcohol or water?
Water has a higher boiling point that alcohol (ethanol). The main reason for this is because water has stronger intermolecular forces holding the molecules together.
Can alcohol and water be seperated by physical means?
Sure! It's called distillation and it's done all the time, especially in Kentucky. Alcohol's boiling point is lower than water's is. If you heat an alcohol-water solution to alcohol's boiling point, the alcohol will boil off leaving the water behind.
What effect does ethanol have on the boiling point of water?
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.
What happens to the boiling point of water when alcohol is added to it?
it cools it
What is the Boiling point of alcohol mixing with water?
The boiling point of alcohol is 173F/78C. Similarly the boiling point of pure water is 212F/100C. Hence the mixing of water and alcohol will have a boiling point that lies between these two ratios.
How do you separate an acid from an alcohol?
water and alcohol have different boiling point; you heat them untill the boiling point of the alcohol( the boiling point of alcohol is lower than water) so that you can collect the evaporated alcohol and left behind the water.
What happens when you boil alcohol?
Alcohol has a lower boiling point than water. Naturally the alcohol evaporates leaving the flavanoids and the water. If you boil 100 % alcohol, then it would act like plain water. It will boil until it all evaporates.
