Sulphuric Acid - an overview ScienceDirect Topics
Sulphuric acid is commonly used but hydrochloric acid is preferred when the scaling potential is high due to CaSO 4, SrSO 4, and BaSO 4. Calcium sulphate is more soluble than BaSO 4 and SrSO 4 . However, since calcium ion is present in natural water sources more abundantly than barium and strontium ions, CaSO 4 is a greater problem.
