Pure water is neutral in nature with pH 7. Due to the presence of dissolved minerals in rain water, the pH increases and becomes alkaline. Alkalinity in water is due to the presence of hydroxide (OH), carbonate (CO3) and bicarbonate
The estimation of water hardness as applied to boiler water and other water is great interest for the chemical industry in general.the determination of water hardness has always been an especially important factor in the manufacturing control of sugar industry,
Solid fuel refers to various forms of solid material that can be burnt to release energy, providing heat and light through the process of combustion. Here we will study about Coal as a solid fuel. The heat available from each type of fuel is
Eriochrome Black T is a complexometric indicator that is used in complexometric titrations, which is mainly used to determine total hardness of Water. In the below photo you can see that in its deprotonated form, Eriochrome Black T is blue. It turns red when
Painting is done in two phases. First, the painters will apply the primer and putty. They will try to fill some of the cracks in the walls and smooth the surfaces. This step can be done almost at any time
A smithy is a place where blacksmiths do their work, heating, and shaping metal, especially to make tools. Smithy or Forging is the oldest shaping process used for producing small articles for which accuracy in size is not so important.
Foundry technology involves molding, melting, and casting of parts; that is, producing castings by filling the prepared molds with molten metal alloys (mostly aluminum). This is a unique primary metal processing method which must be imparted to most engineering students.
Electrical engineering is an engineering discipline concerned with the study, design and application of equipment, devices and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialisation
