Comparing E170II - Calcium hydrogen carbonate vs E170 - Calcium carbonates

Overview

E170II - Calcium hydrogen carbonate

Calcium hydrogen carbonate (E170II) is the dissolved, bicarbonate form of calcium that occurs when carbon dioxide mixes with calcium carbonate in water. It shows up naturally in “hard” water and can be present in some drinks where minerals are balanced for taste and stability. It doesn’t exist as a stable powder; when water is heated or the carbon dioxide escapes, it turns back into ordinary calcium carbonate.

E170 - Calcium carbonates

Calcium carbonates (E170) are white, mineral-based additives used in many foods. They add whiteness, keep powders free‑flowing, adjust acidity, and can add calcium. Regulators in the U.S. and EU allow their use within good manufacturing practice.

Popular questions

  1. How does calcium carbonate neutralize stomach acid?

    Calcium hydrogen carbonate (E170ii) neutralizes stomach acid via an acid–base reaction: Ca(HCO3)2 + 2 HCl → CaCl2 + 2 CO2 + 2 H2O, raising gastric pH.

  2. When calcium carbonate is added to hydrochloric acid?

    Calcium hydrogen carbonate reacts with hydrochloric acid to effervesce (release CO2) and form calcium chloride and water: Ca(HCO3)2 + 2 HCl → CaCl2 + 2 CO2 + 2 H2O.

  3. How does calcium carbonate neutralize acid?

    Its bicarbonate ions consume H+ to form carbonic acid, which decomposes to CO2 and water, leaving a neutral calcium salt (e.g., CaCl2).

  4. Why does calcium carbonate dissolve in acid?

    Acidic H+ converts carbonate/bicarbonate into CO2 and water, removing carbonate from the solid and driving dissolution; calcium hydrogen carbonate itself is soluble in water.

  5. How does calcium carbonate reduce acid rain?

    Calcium hydrogen carbonate isn’t used to prevent acid rain, but carbonate/bicarbonate alkalinity neutralizes acidic waters; industrially, limestone or lime (not Ca(HCO3)2) scrubs SO2 from flue gases, reducing acid‑rain precursors.

  1. Who makes the e170 aircraft?

    In food labeling, E170 refers to calcium carbonates, not an aircraft; they’re made by many ingredient suppliers, typically sourced from mined limestone or produced by reacting calcium hydroxide with carbon dioxide (precipitated calcium carbonate).

  2. Who makes e170 airplane?

    E170 in foods means calcium carbonates, not an airplane; they are supplied by numerous food-grade mineral producers, either mined (ground calcium carbonate) or made by precipitation from calcium hydroxide and CO2.

  3. Calcium carbonates is most likeye to dissolve in water with which characteristics?

    Calcium carbonate is nearly insoluble in neutral water but dissolves in acidic or carbonated water (low pH, high dissolved CO2) by forming calcium bicarbonate.

  4. E170 aircraft who makes?

    On food labels, E170 denotes calcium carbonates rather than an aircraft; they are manufactured by various companies from limestone or via precipitation using calcium hydroxide and carbon dioxide.

  5. How are calcium carbonates formed?

    They form naturally by precipitation of calcium and carbonate ions in water and by biomineralization in shells and eggs, and industrially by reacting calcium hydroxide with carbon dioxide (precipitated calcium carbonate); they can also precipitate from hard water as limescale.
