The emulsion is a word that originated from the Latin word “Mulgeo”, which means “To milk”. Milk is the best example of emulsion, consisting of biphasic liquid systems containing both fat and water. The emulsion can define as the colloidal system, which includes two or more phases of immiscible liquids. In the emulsification process, one …
Water is a solvent that dissolves a variety of substances. It is considered the universal solvent because it can dissolve compounds (like polar molecules and ions) than the available solvents. Its physical and chemical attributes make it an excellent solvent. The chemical formula of water is H2O, i.e. it contains two H-atoms and one O-atom. …
An acid-base titration is one of the titration methods. First and foremost, we should know what titration is and what it requires to conclude the results. A titration is a quantitative chemical analysis that helps in determining an unknown concentration of a solution by the known concentration of a solution. It must be clear that …
The physical state of water has three phases (solid, liquid and gas), depending upon the factors like hydrogen bonding, temperature and pressure. Water is a polar inorganic compound that serves as a universal solvent. It has a neutral pH in a pure state. The melting point of water is 0 degrees Celsius, and the boiling …
The difference between colloid and solution is due to the properties like the solubility of particles, chemical nature and light scattering property. Colloids form when the particles (diameter from 1-1000 nm) are suspended in the dispersion medium. Oppositely, a true solution forms when the solute particles (diameter less than 1 nm) completely dissolve in the …
The concentration of ore is a method of eliminating gangue particles or other impurities. Ore-dressing and benefaction are the alternative names for the term concentration of ore. To obtain a pure metal from ore, the method of ore concentration is a very crucial step. For the extraction of metal, it is necessary to separate ore …
Refining of metal is one of the processes which involves the separation of impurities like sand particles, other metals etc. from the metal of choice. Therefore, refining of metal comes under the science of studying the metal’s physical and chemical properties, called Metallurgy. The methods for refining metals vary according to the type and use …
