Titration is a technique used in chemistry to determine the concentration of a substance in a solution.

• Acid-base titration: involves the reaction between an acid and a base to determine the concentration of either

• Redox titration: involves the transfer of electrons between reactants to determine the concentration of a substance

• Complexometric titration: involves the formation of a complex between a metal ion and a ligand...read more

Bearings typically operate effectively at temperatures ranging from -20°C to 120°C, depending on the type and application.

• Bearings are designed for specific temperature ranges; for example, standard ball bearings can operate between -20°C to 120°C.

• High-temperature bearings, such as ceramic bearings, can withstand temperatures up to 300°C.

• Low-temperature applications may require specialized lubricants to maintain perfor...read more

Reactor main vessel entry requires controlled oxygen levels, typically around 19.5% to 23.5% for safety.

• Oxygen levels below 19.5% can lead to asphyxiation risks.

• Oxygen levels above 23.5% increase fire and explosion hazards.

• Regular monitoring of oxygen levels is essential before entry.

• Use of oxygen sensors is recommended for accurate measurement.
