The measurements showed that the extent of acid concentration gradients is …
Concentrating Sulfuric Acid
Once the acid cools, carefully pour it into an appropriate storage container. Do not leave the cooled acid uncovered too long as Sulfuric acid is hygroscopic and will slowly absorb moisture from the air and dilute itself. At this point, one should have obtained a Sulfuric acid solution which has a concentration somewhere around 95% H 2 SO 4.
