Use of quartz instruments in the laboratory

In a general chemical laboratory, many experimental instruments are quartz glass instruments. Quartz glass does not react with various corrosive chemicals such as ordinary acids and alkalis, and has high stability. Therefore, it is usually used as a chemical instrument, but Quartz glass does not react with all chemical substances. To know which chemical substances react with quartz glass, you must know the main components of quartz glass. The main component of quartz glass is silicon dioxide, which has good stability. This is why quartz glass does not react with many chemicals, but silicon dioxide will harden when it encounters hydrofluoric acid and silicic acid, and if quartz glass encounters these substances, it will be corroded.

In the chemical laboratory, glass rods, funnels, beakers, flasks, test tubes, Erlenmeyer flasks, burettes, transfer tubes, etc. are all made of quartz glass. If the above-mentioned chemical substances are reacted or stored in these containers, these quartz glass Glassware will be damaged.

When doing experiments in the chemical laboratory, what chemical substances should be placed in what containers should not be placed randomly. Although the stability of quartz glass instruments is very good, they should be used with care when using them.
