chemical properties of colloids

Colloidal sols are biphasic in nature. It consists of the dispersed phase and the dispersion medium. In the colloidal solution, each particle is contained within its own surface boundary and therefore has a separate existence from the dispersion mediu..

Brownian movement When a colloidal solution is viewed through a powerful microscope, the colloidal particles can be seen moving in a random zig-zag path. This zig-zag motion of colloidal particles is called Brownian movement. This random motion is due to c..

Chemical properties of iodoform ar..

Chemical Properties - Ethers are relatively inert compounds inspite of the presence of oxygen atom carrying two lone pairs of electrons in their molecules. These are not easily attacked by alkalis, dilute mineral acids, metallic sodium, PCl 5 etc. under ordinary conditions. It i..

Chemical Properties - In the reactions shown by isocyanide, first an electro phile and then a nucleophile add at the carbon to form a species which usually undergoes further transformation..

Since acetic acid contains an alkyl group and an acid moiety (each of the two parts into which a thing is divided), it exhibits the properties of both these group..

Chemical Properties - The noble gases are generally inert and do not participate in the reactions easily. The inertness of noble gases is due to the following reasons. i) The atoms of noble gases have stable closed shell electronic configuration. ii) The noble gases have excepti..

Elemental state and chemical reactivity - Nitrogen is a colorless gas and exists as diatomic. The two nitrogen atoms are held together by triple bond and have very high bond dissociation energy (945 kJ mol - 1 ..
