4.8: Acid-Base Extraction - Chemistry LibreTexts
Apr 7, 2022If no solid forms upon acidification (or if fine crystals or low quantity of solid forms), extract the acidic component back into an organic solvent ( × 3 ). As a general rule of thumb, use one-third as much solvent for the extractions as the original layer (e.g. if using 100 mL aqueous solution, extract with 33 mL organic solvent each time).

Honestly the reaction still proceeds without it, but maybe the sulfuric acid makes the effect more intense. I'll have to try that at some point. But more to your point, trimethyl borate ester is volatile (b.p. = 68 °C) and burns with the green flame characteristic of all boron compounds. It also works with ethanol to form triethyl borate.

Sulfuric Acid | Encyclopedia.com
The lead chamber process involves three primary steps: the combustion of sulfur to produce sulfur dioxide; the conversion of sulfur dioxide to sulfur trioxide; and the reaction of sulfur trioxide with water to make sulfuric acid: S + O 2 → SO 2 2SO 2 + O 2 → SO 3 SO 3 + H 2 O → H 2 SO 4

Extraction of lithium from spodumene - Murdoch University
The highest extraction of 98% was achieved after roasting at 250 °C for 1 hour with 80% excess acid to the stoichiometry of the reaction of spodumene and sulfuric acid. Elongated roasting, roasting at temperatures close to boiling point of the acid and very high amount of excess acid negatively affected Li extraction.

What is purpose of sulfuric acid in iodine extraction?
Sulphuric acid is one of the cheapest choices, but dilute hydrochloric acid will do the same trick. N a H S O X 4 (which I hope is the correct chemical; I never understood the bi- nomenclature and prefer hydrogen sulphate) may work since it is still pretty acidic, but you would need higher concentrations. Acetic acid will probably not work.

Unfortunately, bisulfate ion appears to be a weaker acid than water $(K_{\mat{a}} = 10^{-2})$, so it may not work unless you use a very concentrated amount to obtain enough hydrogen ions. Try it!
