  2. Water-reactive substances - Wikipedia

    en.wikipedia.org/wiki/Water-reactive_substances

    Group 1: Alkali metals Reaction of sodium (Na) and water Reaction of potassium (K) in water. The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.

  3. Sodium carbonate - Wikipedia

    en.wikipedia.org/wiki/Sodium_carbonate

    Sodium carbonate decahydrate (Na 2 CO 3 ·10H 2 O), also known as washing soda, is the most common hydrate of sodium carbonate containing 10 molecules of water of crystallization. Soda ash is dissolved in water and crystallized to get washing soda.

  4. Carbothermic reaction - Wikipedia

    en.wikipedia.org/wiki/Carbothermic_reaction

    A key step in this process is the reduction of sodium sulfate with coal: [3] Na 2 SO 4 + 2 C → Na 2 S + 2 CO 2. The Na 2 S is then treated with calcium carbonate to give sodium carbonate, a commodity chemical. Recently, development of the 'MagSonic' carbothermic magnesium process has restarted interest in its chemistry: [4] MgO + C ↔ Mg + CO

  5. Black snake (firework) - Wikipedia

    en.wikipedia.org/wiki/Black_snake_(firework)

    A white mixture of sucrose and sodium bicarbonate will eventually turn black and the snake will grow about 15–50 centimetres (5.9–19.7 in) long after it is lit. [4] Three chemical reactions occur when the snake is lit. Sodium bicarbonate breaks down into sodium carbonate, water vapor, and carbon dioxide: [2] 2 NaHCO 3 (s) → Na 2 CO 3 (s ...

  6. Spectator ion - Wikipedia

    en.wikipedia.org/wiki/Spectator_ion

    A spectator ion is an ion that exists both as a reactant and a product in a chemical equation of an aqueous solution. [1]For example, in the reaction of aqueous solutions of sodium carbonate and copper(II) sulfate:

  9. Salt metathesis reaction - Wikipedia

    en.wikipedia.org/wiki/Salt_metathesis_reaction

    This reaction usually produces a salt. One example, hydrochloric acid reacts with disodium iron tetracarbonyl to produce the iron dihydride: 2 HCl + Na 2 Fe(CO) 4 → 2 NaCl + H 2 Fe(CO) 4. Reaction between an acid and a carbonate or bicarbonate salt yields carbonic acid, which spontaneously decomposes into carbon dioxide and water. The release ...
