  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. Rebreather - Wikipedia

    en.wikipedia.org/wiki/Rebreather

    In the intermediate reaction, the carbonic acid reacts exothermically with sodium hydroxide to form sodium carbonate and water: H 2 CO 3 + 2NaOH –> Na 2 CO 3 + 2H 2 O + heat. In the final reaction, the sodium carbonate reacts with the slaked lime (calcium hydroxide) to form calcium carbonate and sodium hydroxide: Na 2 CO 3 + Ca(OH) 2 ...

  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. Lye - Wikipedia

    en.wikipedia.org/wiki/Lye

    The reaction between sodium hydroxide and some metals is also hazardous. Aluminium, magnesium, zinc, tin, chromium, brass and bronze all react with lye to produce hydrogen gas. Since hydrogen is flammable, mixing a large quantity of lye with aluminium could result in an explosion. Both the potassium and sodium forms are able to dissolve copper.

  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 ...
