The impact of placement on the quality of sulfuric acid
Thread Content
What impact does 98% having been stored for a period of time have on the sulfuric acid content? There were discrepancies in the analysis results of our samples between the past two days and today, and we are very interested in understanding this issue.
Was it left open? The sulfuric acid concentration must have decreased.
Concentrated sulfuric acid has a strong water-absorbing property; over time, it absorbs moisture from the air, causing its concentration to decrease.
When stored in an open manner, sulfuric acid absorbs moisture from the air, resulting in a lower concentration in the upper portion. If stored in steel equipment, the sulfuric acid concentration at the top rises to 85%, hydrogen is generated, which can cause an explosion.
