Sulfuric acid concentration issue
Thread Content
Can experts roughly determine the sulfuric acid concentration by looking at its appearance, for example, by judging based on the amount of foam produced or the density of the smoke?

Experienced masters can tell, as it is the result of accumulated experience – something that can only be understood but not put into words. :lol:lol:lol
The higher the concentration of sulfuric acid, the thicker its appearance and the darker its color.
In the acid tank, when the acid is as transparent as water, is its concentration high or low? Also, does 98% acid generally have large bubbles or small bubbles?
In our acid tanks, when the acid concentration is high, the liquid becomes as transparent as water; if it gets any higher, smoking occurs
That’s right; take a closer look, and by comparing several times you’ll find the pattern.
By observing the circulation tank, one can see the acid; if its concentration is too low, foam will form, while if it is too high, smoke will appear. Specifically, one needs to read more and summarize.
