2. Purple-K - Wikipedia

   en.wikipedia.org/wiki/Purple-K

   Purple-K, also known as PKP, is a dry-chemical fire suppression agent used in some dry chemical fire extinguishers. [1] It is the second most effective dry chemical in fighting class B (flammable liquid) fires after Monnex (potassium allophanate), and can be used against some energized electrical equipment fires (USA class C fires).

3. Sodium bicarbonate - Wikipedia

   en.wikipedia.org/wiki/Sodium_bicarbonate

   Sodium bicarbonate (IUPAC name: sodium hydrogencarbonate [9]), commonly known as baking soda or bicarbonate of soda, is a chemical compound with the formula NaHCO 3. It is a salt composed of a sodium cation (Na +) and a bicarbonate anion (HCO 3 −). Sodium bicarbonate is a white solid that is crystalline but often appears as a

4. Crack cocaine - Wikipedia

   en.wikipedia.org/wiki/Crack_cocaine

   Sodium bicarbonate (NaHCO 3, common baking soda) is a base used in the preparation of crack, although other weak bases may substitute for it. [7] [8] The net reaction when using sodium bicarbonate is Coc-H + Cl − + NaHCO 3 → Coc + H 2 O + CO 2 + NaCl. With ammonium bicarbonate: Coc-H + Cl − + NH 4 HCO 3 → Coc + NH 4 Cl + CO 2 + H 2 O ...

5. Cocaine - Wikipedia

   en.wikipedia.org/wiki/Cocaine

   Cocaine can be in the form of fine white powder and has a bitter taste. Crack cocaine is a smokeable form of cocaine made into small "rocks" by processing cocaine with sodium bicarbonate (baking soda) and water. [12] [48] Crack cocaine is referred to as "crack" because of the crackling sounds it makes when heated. [12]

6. Baking powder - Wikipedia

   en.wikipedia.org/wiki/Baking_powder

   Baking powder is made up of a base, an acid, and a buffering material to prevent the acid and base from reacting before their intended use. [5] [6] Most commercially available baking powders are made up of sodium bicarbonate (NaHCO 3, also known as baking soda or bicarbonate of soda) and one or more acid salts.

7. Effervescent tablet - Wikipedia

   en.wikipedia.org/wiki/Effervescent_tablet

   The carbon dioxide is generated by a reaction of a compound containing bicarbonate, such as sodium bicarbonate or magnesium bicarbonate, with an acid such as citric acid or tartaric acid. Both compounds are present in the tablet in powder form and start reacting as soon as they dissolve in water. [1] [2] [3] [4]
