Important Points to Remember
A mixture is made up of many substances (elements and/or compounds) in any proportion.
Using the right separation procedures, mixtures may be separated into pure substances.
A solution is a combination of two or more components that is homogenous. The solvent is the primary component of a solution, whereas the solute is the minor.
The concentration of a solution is the quantity of solute contained in the solution/solvent per unit volume or mass.
A suspension is made up of materials that are insoluble in a solvent and contain particles visible to the naked eye. A heterogeneous mixture is a suspension.
Colloids are heterogeneous mixes of particles that are too tiny to discern with the human eye yet large enough to scatter light. Colloids are beneficial in both industry and everyday life. The dispersed phase refers to the particles, whereas the dispersion medium refers to the medium in which they are disseminated.
Elements or compounds can be pure substances. An element is a type of stuff that cannot be broken down into simpler compounds by chemical processes. A compound is a material made up of two or more different types of elements mixed chemically in a certain ratio.
A compound's qualities differ from those of its constituent elements, whereas a mixture reflects the attributes of its constituent elements or compounds.

4. What is Chromatography?
Chromatography is the technique used to separate the solutes that are dissolved in the same solvent. Nowadays, there are many advanced techniques, but chromatography is a laboratory technique to separate the mixture. You can also visit the official website of Vedantu to access NCERT Solutions Class 9 Science Chapter 2 . Students can also download Vedantu’s app. All the resources are available free of cost.
5. What is the difference between mixtures and compounds?
Elements and compounds are mixed to form a mixture.
The constituents in the mixture can be separated.
Components of mixtures have variable compositions.
The mixture displays all the properties of constituent substances.
Elements react to form new compounds.
Compositions of the particles of compounds are fixed.
The separation of the constituents can be done only chemically.
The new substance has different properties.
6. What are the applications where Chromatography is used?
The applications where chromatography is used are separating the colours in the dye, separating pigments from natural colours, separating drugs from the blood. There are many advanced techniques of Chromatography that you will study in detail in the higher classes. There are also courses and subjects in this topic . This is a vast and interesting subject and some students might be interested to take there.
7. What is the Heterogeneous Solution?
A heterogeneous mixture is a type of mixture where the components are not in a uniform composition. Heterogeneous mixtures can be separated physically, and the components are in smaller amounts. Sodium chloride and sand are examples of heterogeneous mixture. These are very important topics when it comes to chemistry. The difference of each should be understood properly so there is no confusion in later stages.
8. Define mixture and solution.
Mixture contains either two or maybe more compounds. These compounds are not chemically combined. They are combined physically while the chemical properties in the mixture remain unchanged. The amount of a substance in a mixture can vary. The solution is a homogeneous mixture because the composition stays uniform throughout the solution. The composition of the solution has solvent and solute, and the solvent always dissolves the solute, and it is in higher quantity.
