The boiling point of ethanol-water mixtures varies depending on the ratio of ethanol to water. Generally, the boiling point of these mixtures falls between the boiling points of pure ethanol (78.37C) and pure water (100C). The boiling point increases as the ethanol content in the mixture increases.

What mixtures could be separated by evaporation?
Mixtures of a solid dissolved in a liquid can be separated by evaporation, where the liquid component is vaporized and the solid component remains behind. Additionally, mixtures of two liquids with different boiling points can be separated by heating the mixture to the boiling point of the component with the lower boiling point, causing it to evaporate while leaving the other liquid behind.
Why is it possible to separate mixtures of liquids by boiling?
It is possible to separate mixtures of liquids by boiling because each component of the mixture has a different boiling point. When the mixture is heated, the component with the lowest boiling point will vaporize first, leaving behind the other component. The vapor can then be condensed back into a liquid, resulting in the separation of the two components.
What are the properties of mixture?
Mixtures contain two or more compounds associated without chemical bonds. Mixtures are homogeneous or heterogeneous. Several mixtures can be separated by physical procedures. Mixtures can have 1, 2 o3 phases.
What types of mixture do fractional distillation separate?
for mixtures that are miscible but have different boiling points
What physical property of matter is used basis in separating mixtures by distillation?
Distillation separates mixtures based on differences in boiling points of its components. When a mixture is heated, the component with a lower boiling point vaporizes first, allowing for separation from the other components that have higher boiling points. This process is used to purify liquids in chemistry and industry.
What is distillation based on to separate mixtures?
Boiling point
Can Filtration can be used to separate mixtures based on their boiling point?
It is not possible; filtration as a separating method is based on the difference between boiling points.
What are the three properties of mixture?
1) There is no fixed composition in mixtures. Eg. Copper and tin are mixed together in variable ratios to form brass. Therefore, it is a mixture. 2) Mixtures do not have a fixed boiling point. This is due to the varying composition of its constituents. Its different constituents have different boiling points, therefore resulting in its unfixed boiling point. 3) Mixtures do not have a fixed boiling point. The reason is similar to the reason given for its unfixed boiling points. Hope this helps (: -babyhamsterx

Why milk has no definite boiling point?
Milk is a complex mixture containing water, proteins, fats, and other components, which can affect its boiling point. The proteins and fats in milk can increase the boiling point compared to water. Additionally, milk can scorch easily due to the presence of sugars, which can also contribute to a variable boiling point.
Results from a change at the boiling point?
A change in boiling point typically indicates a change in the intermolecular forces of a substance. For example, adding a solute to a solvent will usually increase the boiling point due to the formation of new intermolecular interactions. Conversely, a decrease in boiling point may signal a weaker intermolecular force, as seen in solutions or mixtures.

Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.

What is zeotropic?
Zeotropic refers to a mixture in which the components have different boiling points and do not change composition during vaporization. This is in contrast to azeotropic mixtures where the components have the same boiling point and do change composition during vaporization. Zeotropic mixtures can be separated by distillation, whereas azeotropic mixtures require different separation methods.
