What happens when acid reacts with limestone? | .
Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3 ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will

An alternative approach is to use limestone for the neutralization process. The fluidisedbed limestone neutralisation process has been developed to neutralise free acid and remove Fe(III) and Al(III) concomitantly (du Plessis and Maree 1994; Maree and du Plessis 1994; Maree et al. 1992; Maree et al. 1996a,b; Maree 1997). Previous studies showed that: • Complete neutralisation of discard ...

Limestone for pH Adjustment in Industrial Wastewater ...
The neutralization process occurs when strong acids, in intimate contact with limestone chips, react with Calcium Carbonate (CaCO 3, the primary constituent of limestone) to form water, carbon dioxide, and calcium salts. The following depicts the neutralization of hydrochloric acid by limestone. CaCO 3 + 2HCl → CaCl 2 + CO 2 + H 2 O. Due to the presence of other calcium products in the ...
