What else can I help you with?
The laboratory process of distillation does not involve?
liquids with the same boiling points. because they would evaporate at the same time leaving you without a solution.
If you have a very heat sensitive liquid that will decompose if it is overheated How could you purify it by distillation without applying excessive heat?
You could perform vacuum distillation at a lower temperature by lowering the pressure in the system, which reduces the boiling point of the liquid. This allows you to distill the liquid at a temperature below its decomposition point. Another option is to use a fractional distillation setup to separate the liquid components based on their boiling points, allowing you to collect the desired component without overheating it.
Under what basic principle is fractional distillation employed in separating mixtures.?
Fractional distillation is based on the principle that every liquid has a different boiling point. None of the mixtures of two or more miscible liquid have the same boiling point in the universe. So a mixture of two miscible liquids will have different boiling points and on the basis of this difference, the components of the mixture can be separated by the fractional distillation.Fractional distillation is accomplished by applying varying degrees of heat (or cooling, depending on how you investigate it) to the process of separating different substances. Fractional distillation is applied broadly in the petrochemical industry to recover hydrocarbons of differing boiling points. In brief, if we heat a mixture of hydrocarbons sufficiently, all of those that have boiling points lower than the setting will evaporate or boil off of the inflow to the unit. As vapor or gas they rise. And as the temperature is reduced in stages as we move higher up the structure or tower (which some call a cracking unit), those substances with boiling points higher will begin to condense out. More volatile substances will continue higher in the unit before cooling is sufficient to get them to condense, and this will permit substances of even greater volatility to rise further before being condensed and recovered. It should be noted that in petrochemical refining, the chemist (petrochemist) is a key player, and nothing proceeds without him or her. But fractional distillation is a physical process, and not a chemical one. Links can be found below to check facts and learn more.
If ethyl alcohol boils at 79 degrees Celsius a physical or chemical change?
Boiling of ethyl alcohol at 79 degrees Celsius is a physical change. It is a reversible process where the alcohol changes from liquid to vapor state without undergoing a chemical reaction.
Ideal distillation curve?
An ideal distillation curve represents the percentage of a component in a mixture that evaporates at each temperature during distillation. It shows a smooth, continuous increase in the fraction of liquid distilled over a range of temperatures, without plateaus or irregularities, resulting in sharp separation of components based on their boiling points. This curve is theoretical and serves as a reference point for evaluating the efficiency of an actual distillation process.
How do you get salt from salty water without evaporation?
Distillation is a method, but it is also based on boiling and condensation.
How can water be purified without boiling it?
Water can be purified without boiling it by using methods such as filtration, distillation, chlorination, or using ultraviolet light. These methods help remove impurities and make the water safe to drink.
The laboratory process of distillation does not involve?
liquids with the same boiling points. because they would evaporate at the same time leaving you without a solution.
How is sublimtion different from distillation?
distillation involves a mixture of substances, boiling and separating one of those. Sublimation is one single substance like iodine changing from a solid to a gas without going thru the liquid phase.
If you have a very heat sensitive liquid that will decompose if it is overheated How could you purify it by distillation without applying excessive heat?
You could perform vacuum distillation at a lower temperature by lowering the pressure in the system, which reduces the boiling point of the liquid.

Is it possible to boil water at room temperature of 20 degree celsius without heating it explain?
Yes it is possible. Boiling takes place when the saturated vapour pressure becomes equal to the surrounding pressure. So by reducing pressure over the surface of liquid even at 20 deg celsius it is possible to boil.
Is distillation a chemical change or a physical change?
Distillation is a physical change. It involves the separation of components in a mixture based on differences in their boiling points, without changing the chemical composition of the substances.
Boiling point of water at absolute 0 pressure?
At absolute zero pressure, water will boil at 0 degrees Celsius. This is because at zero pressure, water can boil into vapor without needing to reach its normal boiling point of 100 degrees Celsius under standard pressure conditions.
Is lithium a solid at boiling point?
No. Solids do not boil, but they may sublime, which is when a solid goes directly into the gas phase without melting first. However, lithium does not sublime. Its melting point is 180.54 degrees Celsius, and its boiling point is 1342 degrees Celsius. So lithium is a liquid before reaching its boiling point.
What would most likely be the temperature of boiling water?
Water boils at 100 degrees Celsius or 212 degrees Fahrenheit. Unless, of course, you are boiling it by putting it in a vacuum without air and in that case it could be any temperature.
