How to prepare 99% concentrated sulfuric acid from 98% concentrated sulfuric acid? What issues need special attention during the preparation process?
It was prepared using 20% fuming sulfuric acid; this should be relatively simple. Just be careful to stay safe and avoid getting it on your body. The temperature change is likely to not be very significant! ! !
Are there any other methods besides this? We don’t have 20% fuming sulfuric acid either
Using other methods will introduce other substances! ! !
