Dilution of concentrated sulfuric acid is a common procedure because it is much denser than water. If water is directly added to concentrated sulfuric acid, a lot of heat will be released, which can easily lead to accidents and cause great harm to people. So, what is the concentrated sulfuric acid dilution equipment? What are the precautions for dilution of concentrated sulfuric acid?

Concentrated sulfuric acid releases a lot of heat when dissolved in water. The density of water is lower than that of concentrated sulfuric acid. Therefore, if water is poured into concentrated sulfuric acid, the water will float on top of the concentrated sulfuric acid and boil, causing droplets to splash. Therefore, when the concentrated sulfuric acid is diluted, the concentrated sulfuric acid should be slowly injected into the water along the wall of the container, and the heat should be diffused by continuous stirring with glass rod. Do not inject water into concentrated sulfuric acid.
What is the dilution equipment for concentrated sulfuric acid?
When the concentrated sulfuric acid is diluted, the concentrated sulfuric acid is usually slowly injected into the water along the wall of the container (the flask is emptied with a glass rod), and the heat generated by dilution is released by continuous stirring.
When diluting concentrated sulfuric acid, wear mask, glasses, rubber gloves and plastic apron for protection. Be sure to use thick plastic buckets and cans. First, half a bucket of water is put into a plastic bucket, and then concentrated sulfuric acid is slowly poured into the bucket along the inner wall of the barrel, and constantly stirred to dissipate heat. If the acid water is too hot, do not add concentrated sulfuric acid. It can be mixed into the soil of seedling tray. Typically, 3 kg of water and 1 kg of concentrated sulfuric acid are diluted to nearly 25% of dilute sulfuric acid. 25% dilute sulfuric acid cannot be used for watering seedlings! It can be mixed with proper amount of seedbed soil to adjust acid. When diluting concentrated sulfuric acid, it is necessary to slowly pour the concentrated sulfuric acid into the water and stir it continuously to dissipate heat. Do not pour water into concentrated sulfuric acid. If water is poured into concentrated sulfuric acid, the concentrated sulfuric acid will immediately boil and splash, which may cause burns and disfigurement.
