Mining of Sulphur - Frasch Process A Frasch pump consisting of a set of three concentric pipes is sunk deep into the sulphur bed Super heated water at 170 0 C under pressure is pumped in through the outermost pipe Sulphur in the sulphur bed melts due to its contact..

The term spontaneity means the feasibility of a process. A process which can take place by itself under the given set of conditions once it has been initiated if necessary, is said to be a spontaneous process. The spontaneous processes are called f..

Oil or molten fat is taken in an iron pan fitted with a stirrer. It is then treated with lye (any strong alkaline solution, like potassium hydroxide used for washing or cleansing). Stirring is continued till the soap begins to set. After solidification in frames, it is cut into slabs and..

Introduction - When a chemical reaction gets started the reactants are present in the initial stage, but as the reaction proceeds, the concentration of the reactants decreases and that of products increases. Finally, a stage is reached when no further change in concentration of reactants and produc..

The Open Hearth Process - A mixture of cast iron, scrap iron, iron ore (haematite) and lime is melted in an Open Hearth Furnace. The hearth is lined with silica (SiO 2 ) or calcined dolomite (CaO.MgO) based on whether the impurities present in cast iron. If the impurities are manganese an..

A mixture of cast iron, scrap iron, iron ore (haematite) and lime is melted in an Open Hearth Furnace. The hearth is lined with silica (SiO 2 ) or calcined dolomite (CaO.MgO) based on whether the impurities present in cast iron. If the impurities are manganese and silicon, silica lining is used. Ca..

Cement absorbs water on mixing to form a gelatinous mass. This sets to a hard mass and is very resistant to pressure. This process is called the setting of cement. This simple looking process involves a complicated set of reactions of hydration and..

. Note: The fast-setting tricalcium aluminate is removed to slow down the setting process. A quick setting will give rise to crystalline hydrated calcium aluminate. A slower setting yields the colloidal gel that imparts greater strength to the ..

"Electrolysis is the electrolytic dissociation and decomposition of an electrolyte (electrovalent substance), by the passage of a direct current or electricity through its aqueous or molten form." The process of electrolysis is not a simple chemical reaction of mix and match. As electrici..
