Alcohol has one O–H bond which is polar, but a large portion of the molecule is made up of C–H bonds which are nonpolar. Alcohol molecules do not attract each other as strongly as water molecules and ...
Water molecules are polar molecules ... This means that the molecule itself is non-polar due to symmetry.
The sucrose molecules dissolve as they are separated from each other and mix into the water. The water is polar, so it dissolves the polar color and sugar. The alcohol has a polar area but a larger ...
When a charged object such as a rubber balloon is brought close to a fine stream of a polar liquid, the stream is attracted toward the electrical charge. If the same charged object is brought close to ...
soluble in water and other polar solvents insoluble in non-polar solutions (eg hexane) All non- polar covalent substances are: soluble in non-polar solvents insoluble in water and other polar ...
The film discusses the importance of solutions in various aspects of life and science. It explains how solutions differ from suspensions and colloids, illustrating the process of dissolving substances ...
