Do You Add Sulfuric Acid to Water or Vice Versa?
17/8/2019· Whether you add acid to the water or water to the acid is one of those things that''s important to remeer, but you may need to figure out. Sulfuric acid (H 2 SO 4) reacts very vigorously with water in a highly exothermic reaction.If you add water to concentrated
Process of producing hydrocarbon oil concentrates of …
A fluid concentrate of about 17-20% barium sulfonate-barium chloride complex was obtained. If dilute sulfuric acid had been used instead of dilute hydrochloric acid the product would have been an oil solution of normal barium sulfonate.
Conversion of Moroccan phosphogypsum waste into …
The phosphoric acid production in the world generates a large amount of phosphogypsum with the emission of toxic acid fluorine gas into the atmosphere, which forms a significant source of environmental contamination. In this work, a novel and a simple procedure allows converting phosphogypsum waste by using hydrofluoric acid and sodium fluoride into valuable products. The obtained results
