Heating the mixture in chromatography helps to increase the solubility of the components in the mobile phase, making them more likely to interact with the stationary phase and separate properly. Additionally, heating can reduce the viscosity of the mobile phase, allowing for better flow rates and improved separation efficiency.

What is role of ninhydrin in thin layer chromatography?
Ninhydrin is used as a visualization reagent in thin layer chromatography to detect amino acids and other compounds that contain primary amines. When sprayed onto the developed TLC plate and heated, ninhydrin reacts with primary amines to form colored products, allowing for visualization and identification of the separated compounds.
How do you separate the mixture solute?
Mixtures of lipids can be separated using a variety of techniques. The simplest method is thin layer chromatography. Others include solid-phase extraction and high-performance liquid chromatography.
When sulphur and iron are heated in a china dish why do they stick to it?
Because it has been melted and it only can be separated in chemical method
Salt water can be separated by evaporation?
Yes, salt water can be separated by evaporation. When the salt water is heated, the water evaporates, leaving the salt behind. The vapor can then be collected and condensed back into liquid water, leaving the salt separated.
Why the NaOH solution is heated before adding BaCl2 in the two solutions method for determination of purity of NaOH sample?
Why the NaOH is heated before adding in BaCl2 for determination of purity of NaOH sample?
What type of mixture can only be separated by evaporation?
homogeneous and heterogeneous mixtures are separated by evaporation
Is heated sulfur and iron fillings is substance or mixtures?
Heating sulfur with iron fillings lead to the formation of iron sulfide - a chemical compound.
How do you separate the components of ink?
The components of ink can be separated by chromatography, which involves using a solvent to dissolve the ink and then separating the components based on their different affinities for the stationary phase. Another method is distillation, where the ink is heated to its boiling point and the components are collected as they evaporate and condense back into liquid form.
What is role of ninhydrin in thin layer chromatography?

When sprayed onto the developed TLC plate and heated, ninhydrin reacts with primary amines to form colored products, allowing for visualization and identification of the separated compounds.
What are the different ways of separating of mixtures?
5 ways to separate mixtures are distillation, filtration, condensation/distillation, Evaporation, chromatography, centrifuging and magnetism.Chromatography - To separate different coloured dyes. The dyes travel up the chromatography paper at different distances before they cannot remain in solution. The more soluble dyes move further up than the less soluble ones, hence separating from each other.Distillation - to separate and collect a liquid from a solution of a soluble solid. The solution is heated in a flask until the liquid boils. The vapour produced passes into the condenser where it is cooled and condenses to a liquid. The pure liquid (distillate) is collected in a beaker.Evaporation - This method is suitable to separate a soluble solid from a liquid. If the solution is heated, the liquid evaporates leaving the solid behind.Fractional Distillation - This is a special type of distillation used to separate a mixture of liquids. Different liquids boil at different temperatures. When heated, they boil off and condense at different times. The apparatus features a fractionating column, which ensures that only the liquid boils at its boiling point will pass into the condenser.Filtration - To separate an insoluble solid from a liquid. The solid remains in the filter paper and the liquid goes through the paper into the beaker.Some of the example mixtures that can be separated using the above mentioned techniques:(1) separating dyes in inks, or chlorophyll in plants (ethanol as solvent) - chromatography;(2) separating sand from water - filtration;(3) separating ethanol and water - fractional distillation;(4) separating water from ink - simple distillation;(5) separating salt from water - evaporation

What is a example of separation using physical change?
Most materials in our world are mixtures. Very few materials are pure substances. The art of separating mixtures is important because it enables us to isolate pure substances. Mixtures are either homogeneous or heterogeneous. Homogeneous mixtures are uniform in composition. Heterogeneous mixtures are not. Salt water is a mixture of water and NaCl and is homogeneous if thoroughly mixed, with all the salt dissolved. Oil in water is a heterogeneous mixture. Both types of mixtures can be separated into their component parts by physical means. A salt water mixture can be separated by distilling or evaporating the water and collecting the salt residue. An oil and water mixture will separate into an oil layer and a water layer because the materials are not attracted to one another and gravity "pulls" the denser water beneath the less dense oil. Settling, filtration, chromatography, and manual methods are all means of separating the components of a mixture. Choice of method depends on the type of mixture and the characteristics of its components.
What is similar to baking powder?
bicarbonate of soda.It produces carbon dioxide when heated in damp cake mixtures.
Is Ceramic is an alloy?
no. alloys are mixtures of metals. Ceramics are formed from clays that have been heated and partly vitrified
What procedure did you use to separate plant pigments?
We used a technique called chromatography to separate plant pigments. This involves placing a sample of the pigment on a solid medium, such as paper or a column, and allowing a solvent to move through the medium. As the solvent travels, it carries the different pigments at different rates, resulting in their separation based on their different affinities for the solvent and the medium.
What is the apparatus called for containing liquid mixture for heating?
There are many kinds of liquid mixtures, and many kinds of containers in which such mixtures can be heated, which would include such things as pots, flasks, cauldrons, alembics, etc.
What substances can be separated by evaporation?
Substances that can be separated by evaporation include mixtures of a solid dissolved in a liquid, such as salt dissolved in water. When the liquid is heated, it evaporates, leaving behind the solid substance. Evaporation is a common method used in separation processes in chemistry and industry.
