Calcium carbonate (CaCO_3) reacts with stomach acid (HCl, hydrochloric acid) according to the following equation: CaCO_3(s)+2HCl(aq)--->CO_2(g)+H2O(l)+CaCl_2(aq) A typical antacid contains CaCO_3. Calcium carbonate CaCO_3 reacts with stomach acid (HCl, hydrochloric acid) accordi...
manganese carbonateleachingleaching kineticsmanganese sulfateIn this study, a method for preparing pure manganese sulfate from low-grade ores with a granule mean size of 0.47 mm by direct acid leaching was developed. The effects of the types of leaching agents, sulfuric acid concentration, reaction ...
We delivered as EPC contractor the 300 KTPA phosphoric acid plant for Phase I of the project. The plant is located in an alpine cold region which comes with robust freezing protection design. The feed, which is iron ore tailing after floatation, contains residual phosphorous, and presents treme...
b. If sulfuric acid (H2SO4) is added to this solution, will a color change be observed? If so, how does the addition of sulfuric acid result in a color change? Explain by showing the effect of the addition of H2S Chalk contains calcium carbonate. What would...
Sulfuric acid speleogenesis (SAS) produces porosity in carbonate aquifers where anoxic, hydrogen-sulfide (H2S)-bearing fluids interact with air-filled voids or oxygenated ground water to produce sulfuric acid (H2SO4). Ancient karst features formed as a result of SAS include some of the world's...

Imagine that sulfuric acid is spilled on a lab bench. It can be neutralized by sprinkling sodium bicarbonate on it and then mopping up the resultant solution. The sodium bicarbonate reacts with sulfuric acid as follows: {eq}2NaHCO_3 (s) + H_2SO_...
to be recover. One way of producing HCl is by reacting sulfuric acid with a chloride salt. In the denominated “Leblanc Process” from the 18thcentury, sodium chloride was used to form sodium sulfate which was afterward transformed in sodium carbonate by reaction with calcium carbonate and ...
