Various methods of emulsions to test the type of emulsion are as follows: a) Microscopic methods: To a small amount of the given emulsion, a few drops of water are…
Applications of emulsions: Emulsions are useful in a number of ways. Some of the applications are discussed below: a) In the metallurgical processes, the concentration of ore by forth floatation…
Colloids play a very significant role in nature and in our daily life. Some of the important applications of colloids are discussed below: 1) Medicines: Medicines in colloidal form are…
The colloidal system constituting the liquid as the dispersed phase and the solid as the dispersion medium is known as gel. There are some sols that have a high concentration…
Catalyst is a substance which can change the speed of a chemical reaction without being used up in that reaction and the phenomenon is known as catalysis. Catalyst is divided…
Homogeneous catalyst: If the catalyst is present in the same phase as the reactants, it is called a homogeneous catalyst and this type of catalyst is called homogeneous catalysis. Heterogeneous…
Zeolites are aluminosilicates i.e. three dimensional net work silicates in which some silicon atoms are replaced by aluminium atoms. They are found in nature as well as synthesized in the…
All biological reactions are catalyzed by special catalyst called enzymes. Thus enzymes are defined as biological catalyst. Chemically all enzymes are globular proteins. However, some enzymes are also associated with…
Various type of radioactive material like plutonium can be used as a fissionable material. However, ordinary uranium consists only of about 0.7 percent of U235 and it is extremely difficult…
As we know 92U238 is bigger in size so it will not breakup unless the energy of bombarding neutrons is more than 1.2 MeV. Such neutrons are called fast neutrons.…
