  2. Magnesium carbonate - Wikipedia

    en.wikipedia.org/wiki/Magnesium_carbonate

    Like many common group 2 metal carbonates, magnesium carbonate reacts with aqueous acids to release carbon dioxide and water: MgCO 3 + 2 HCl → MgCl 2 + CO 2 + H 2 O MgCO 3 + H 2 SO 4 → MgSO 4 + CO 2 + H 2 O

  3. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    Magnesium has a mild reaction with cold water. The reaction is short-lived because the magnesium hydroxide layer formed on the magnesium is almost insoluble in water and prevents further reaction. Mg(s) + 2H 2 O(l) Mg(OH) 2 (s) + H 2 (g) [11] A metal reacting with cold water will produce a metal hydroxide and hydrogen gas.

  4. Carbonic acid - Wikipedia

    en.wikipedia.org/wiki/Carbonic_acid

    At ambient temperatures, pure carbonic acid is a stable gas. [6] There are two main methods to produce anhydrous carbonic acid: reaction of hydrogen chloride and potassium bicarbonate at 100 K in methanol and proton irradiation of pure solid carbon dioxide. [3] Chemically, it behaves as a diprotic Brønsted acid. [8] [9]

  5. Carbonation - Wikipedia

    en.wikipedia.org/wiki/Carbonation

    In chemistry, the term is sometimes used in place of carboxylation, which refers to the formation of carboxylic acids. In inorganic chemistry and geology, carbonation is common. Metal hydroxides (MOH) and metal oxides (M'O) react with CO 2 to give bicarbonates and carbonates: MOH + CO 2 → M(HCO 3) M'O + CO 2 → M'CO 3

  6. Reactivity series - Wikipedia

    en.wikipedia.org/wiki/Reactivity_series

    The most reactive metals, such as sodium, will react with cold water to produce hydrogen and the metal hydroxide: 2 Na (s) + 2 H 2 O (l) →2 NaOH (aq) + H 2 (g) Metals in the middle of the reactivity series, such as iron , will react with acids such as sulfuric acid (but not water at normal temperatures) to give hydrogen and a metal salt ...

  7. Transition metal carbonate and bicarbonate complexes

    en.wikipedia.org/wiki/Transition_metal_carbonate...

    To a single metal ion, carbonate is observed to bind in both unidentate (κ 1-) and bidentate (κ 2-) fashions. [5] In the covalent bond classification method, κ 1-carbonate is anX ligand and κ 2-carbonate is an X 2 ligand. With two metals, the number of bonding modes increases because carbonate often serves as a bridging ligand.

  8. Carbonated water - Wikipedia

    en.wikipedia.org/wiki/Carbonated_water

    Bonds in carbonic acid are more easily broken at high temperatures resulting in the generation of water and gaseous carbon dioxide. Thus sparkling water at lower temperatures (far right) holds more carbonation than at high (far left). [18] Carbon dioxide gas dissolved in water creates a small amount of carbonic acid (H 2 CO 3): H 2 O (l) + CO 2 ...

  9. Amphoterism - Wikipedia

    en.wikipedia.org/wiki/Amphoterism

    Metal oxides which react with both acids as well as bases to produce salts and water are known as amphoteric oxides. Many metals (such as zinc, tin, lead, aluminium, and beryllium) form amphoteric oxides or hydroxides. Aluminium oxide (Al 2 O 3) is an example of an amphoteric oxide. Amphoterism depends on the oxidation states of the oxide.
