This is a STI Technical Note for Sulfuric Acid concentration and ph, STI-TN-20170818-1, from STI about “Calculating pH from Sulfuric Acid concentration”.
In this note, STI shows
- How to calculate pH value from a given weight concentration of Sulfuric Acid, and vice versa.
- A graph showing the relationship between the pH value to a given weight concentration in %.
As a summary, the scrubber effluent with pH=~3.0 is a sulfuric acid solution with ~10-4% of weight concentration.
