The preparation of HCL from concentrated sulfuric acid is a common operation in chemical experiments, but there are also certain risks, so special attention should be paid to safety matters during the operation. Before

operation, it is necessary to make full experimental preparation, including wearing protective equipment, ensuring that the experimental table is clean and tidy, and ensuring that the laboratory is well ventilated. During the experimental operation, it is necessary to carefully and slowly add sulfuric acid to avoid violent chemical reactions. At the same time, it is necessary to be vigilant at all times and pay attention to the laboratory situation. Once an abnormal situation occurs, corresponding safety measures should be taken quickly to avoid accidents.
After the operation is completed, the
should clean up the experimental table and equipment in time to ensure that the chemical waste is properly treated to avoid harm to the experimental environment and personnel. In general, the preparation of HCL by concentrated sulfuric acid is an operation that requires a high degree of vigilance and caution. Only by strictly observing the safety operation procedures can the experiment be carried out smoothly and the safety and stability of the laboratory be guaranteed.
