pH measurement is one of the most important chemical values, its determination and control is a standard activity in many industrial applications, including water treatment and purification. The desired pH level in the neutralization process can be adjusted by adding solutions of acidic and alkaline substances (bases).
Hydrochloric acid is a strong inorganic acid, the salts of which are called chlorides, the most famous being sodium chloride (NaCl) (table salt). The acid is widely used in the chemical industry, mining and metallurgy. In the process of water purification, it is used successfully in correction where the pH value of raw water exceeds […]
Sodium hydroxide (also known as caustic soda, sodium hydroxide or lye) is a solid, hygroscopic white substance. This strong base (pH = 14 at c = 1 mol / l) dissolves slightly in water with heat-releasing, also reacts easily with carbon dioxide in the air, and is therefore stored in hermetically sealed containers to avoid […]
The proposed technical sulfuric acid (96%) is one of the strongest acids and is very corrosive, it is a colourless (brownish), oily, very viscous and hygroscopic liquid with different concentrations. It is suitable for use due to its low influence of ambient temperatures. In the process of water purification, it is used successfully in correction […]
