What can chromatography be used for?
The uses of chromatography are important in checking the purity of oils extracted from plants, which are often used in the medicine industry. It shows all the different colours of chemicals in the mixture can be used to compare the elements of two mixtures.
What method of separating mixtures be used to separate oil from oil-water mixture?
Most of the components of petroleum are separated by Fractional distillation.
What types of mixtures can be used by gravity separation?
These mixtures must have large differences between densities.
What is paper chromatographic separation in chemistry?
Paper chromatography is an analytical chemistry technique for separating and identifying mixtures that are or can be colored, especially pigments. This can also be used in secondary or primary colors in ink experiments. This method has been largely replaced by thin layer chromatography, however it is still a powerful teaching tool. Two-way paper chromatography, also called two-dimensional chromatography, involves using two solvents and rotating the paper 90° in between. This is useful for separating complex mixtures of similar compounds, for example, amino acids.
Can chromatography be used to separate mixtures?
Chromatography is used in case of an investigation as in the analysis of poisoned food, chromatography can help find individual components.
When can solution and filtration be used as a method of separating mixtures?
An insoluble solid can be separated by filtration from the liquid.
What are the ways of separating mixtures like sifting?
Sieving is largely used in laboratories and industry for separation.
Which method of separation is commonly used for separating mixtures of colored substances?
Chromatography

What is the principle used in separation of mixtures?
separating an insoluble solid from a liquid: decantation, filtration separating a dissolved solid (solute) from a solution: evaporation, crystallization separating the solute and solvent from a solution: simple distillation separating a mixture of two miscible liquids: fractional distillation
Why do we need to separate the different materials in a mixture?
We separate mixtures for many things. It can be used for cleaning (filtering) our water. This is done by FILTRATION;when the substances in a mixture have different particle sizes, they are separated by filtration. The more different the properties are, the easier it is to separate the substances.Read more: SEPARATING MIXTURES http://www.infoplease.com/dk/science/encyclopedia/separating-mixtures.html#ixzz3OjF9dZjT
What method of separating mixtures be used to separate oil from oil-water mixture?
Most of the components of petroleum are separated by Fractional distillation.
Why distillation is the most effective way in separating mixtures?
Its not always, crystallization is often used when the mixed materials have similar boiling points. Distillation is only effective when the boiling points are very different. Electrolysis is much more useful in separating alloyed metals into their components. etc.
What are the methods used for separating solid from liquid mixtures?
The process that separates insoluble substances from a liquid is filtration. For more information: http://antoine.frostburg.edu/chem/senese/101/matter/separation.shtml
What is the function of bibulous paper?
Bibulous paper is used in laboratories to absorb excess liquid from samples during experiments. It is highly absorbent and helps in separating solvents from substances. This paper is commonly used in chromatography techniques for analyzing mixtures.
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.
How do you separate oxygen ammonia hydrogen mixture?
Various methods could be used to separate such a mixture. However, one suitable method which is widely used for separating gas mixtures is fractional condensation. This method relies on differences in boiling points to separate the components.
