The film explores the concept of solutions in chemistry, defining key terms such as solute and solvent. It illustrates how solute particles dissolve and disperse uniformly in a solvent, highlighting ...

Science presenter Jon Chase demonstrates that a large piece of expanded polystyrene will dissolve in a very small volume of propanone. He defines the terms solute, solvent and solution. By dissolving ...

London dispersion forces have been cited as an important factor in protein folding, drug–receptor interactions, and catalyst selectivities. However, careful analysis of a model system finds that the ...

A new theory 'demystifies' the crystallization process and shows that the material that crystallizes is the dominant component within a solution -- which is the solvent, not the solute. The theory ...

Chromatography is used to separate the given components of a mixture that have differing solubilities in a solvent. It can be used to separate coloured substances in a mixture, like the inks in this ...

The NCERT questions given at the end of each chapter are not only important for examinations but also helpful to clearly understand all the concepts. That is why students are strongly recommended to ...
