In general, for an acid AH n at concentration c 1 reacting with a base B(OH) m at concentration c 2 the volumes are related by: n v 1 c 1 = m v 2 c 2. An example of a base being neutralized by an acid is as follows. Ba(OH) 2 + 2H + → Ba 2+ + 2H 2 O. The same equation relating the …

Waste disposal methods for hydrofluoric acid

18/3/2011, · If you do not need to treat for fluoride, you can neutralize the acid with caustic, instead. You will get much less sludge. Do a bench scale test first to determine the appropriate dilution factor, if any. If the acid is really strong it may heat up excessively during neutralization, causing the release of HF vapors, and possible damage to equipment.

Neutralization Chemicals

The basic principle of neutralization of a base or acid requires either hydroxide ions (OH-) in a base for neutralizing an acid or hydrogen ions (H+) in an acid for neutralizing a base. Neutralization with Acid Since most chemicals listed above will work to neutralize waste streams, cost considerations will often determine the selection.
