How to prepare dilute sulfuric acid
When preparing dilute sulfuric acid, the following three points should be kept in mind: Both 98% concentrated sulfuric acid and the dilute acid that results from its preparation are highly corrosive. 98% sulfuric acid is also highly absorbent and can cause skin burns; therefore, it is necessary to wear appropriate protective gear when handling it. A large amount of heat is generated during the dilution of concentrated sulfuric acid, so it is absolutely forbidden to pour water into concentrated sulfuric acid – instead, the concentrated sulfuric acid must be added to water slowly. The addition process must also be carried out gradually.
It also needs to be stirred continuously; if the dilute sulfuric acid used is for testing, it also requires calibration
The safest way to prepare dilute sulfuric acid is to go to a sulfuric acid factory and ask the operators about the precautions to take
