WebApr 13, 2024 · Consequently, in some cases carbonate depletion is faster than that of the sulfides, which may not ensure acid neutralization at the long-term scale. Depending on the mineralogical composition of the mine waste, silicate minerals can contribute to the total neutralization potential, including biotite, chlorite, plagioclase, muscovite, and ... WebJun 5, 2024 · Stated differently, less energy is released from making acetate ion from acetic acid than from making chloride ion from hydrochloric acid (or water from hydronium ion). Despite the lesser tendency of acetic acid to ionize, the overall stoichiometry of the two reactions is the same--as pointed out in a comment by the OP.
