In the laboratory, the synthesis of compounds need to follow certain procedures, especially for some dangerous compounds. Sodium thiosulfate is one such compound, which requires special care when synthesized in the laboratory. Let's take a look at the precautions and detailed steps for the synthesis of sodium thiosulfate.
Precautions for
synthesis of sodium thiosulfate:
1. Laboratory operating procedures When
conduct synthetic experiments, they must first be familiar with laboratory operating procedures, understand the nature of chemicals and safety precautions, and take personal protective measures.
2. Storage and handling of chemicals
Sodium thiosulfate is a toxic chemical and should be stored in a dry and ventilated place, and stored separately from acids, oxidants and other chemicals to avoid accidents. Goggles, gloves and lab coat are required for use and handling.
3. Precautions for operation
When conducting synthesis experiments, it is necessary to pay attention to careful operation to avoid chemical spilling and gas release. After the experiment, waste liquid should be treated in time to keep the experimental environment clean and tidy.
the steps of
synthesis of sodium thiosulfate:
1. configure the right amount of sodium thiosulfate raw material
first need to prepare a sufficient amount of thiosulfuric acid and alkaline sodium hydroxide, according to a certain molar ratio into the reaction vessel.
2. Heating the reaction
The thiosulfuric acid and sodium hydroxide in the reaction vessel were heated, and the color and physical state of the reaction were observed.
3. Filtration of Solid Product
The solid product produced after the reaction was filtered to obtain a crude product of sodium thiosulfate.
4. Crystallization Purification
The crude product is subjected to crystallization separation and purification treatment to obtain crystalline pure sodium thiosulfate.

in the synthesis of sodium thiosulfate in the whole process, the need to strictly follow the experimental procedures, to prevent the danger of chemicals, to ensure the safety of the laboratory environment. Only by attaching great importance to the matters needing attention and strictly following the steps can we successfully synthesize high purity sodium thiosulfate.
