Hydrochloric acid is used to convert high-grade scheelite concentrate (CaWO4) and crude sodium tungstate to tungstic acid, which in turn, can be used to produce tungsten metal and chemicals. Hydrochloric acid is also used in uranium and zirconium processing, solution mining of borate ores, as a pH regulator in the froth flotation of potash ores, and in rare earth extraction from bastnasite.
Limestone-hydrochloric acid Process React hydrochloric acid with calcium carbonate (limestone). 2HCl + CaCO3 → CaCl2 + H2O + CO2 Natural brine process Purifiion of naturally-occurring brines (such as salt lakes) by removing magnesium with adding Ca.
The concentration of Ca(OH) 2 (s) does not appear in the equilibrium constant expression because it is always present as the pure solid (activity is 1), no matter how much or how little of it is present. A saturated solution of Ca(OH) 2 can be prepared by the reaction of calcium metal with water.

Hydrochloric Acid Summary Hydrochloric acid is an important and widely used chemical. The largest end uses for hydrochloric acid are steel pickling, oil well acidizing, food manufacturing, producing calcium chloride, and ore processing. Hydrochloric acid is a
An acid is a molecule or ion capable of donating a proton (hydrogen ion H+) (a Brønsted–Lowry acid), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid).[1] The first egory of acids are the proton donors, or Brønsted–Lowry acids. In the special case of aqueous solutions, proton donors form the
Metal compound A reacts with dilute hydrochloric acid to produce effervescence. The gas evolved extinguishes a burning candle. Write a balanced chemical equation for the reaction if one of the compounds formed is calcium chloride. Answer: When calcium carbonate reacts with hydrochloric acid, it produces carbon dioxide gas with effervescence.
