  2. Sodium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Sodium_hydroxide

    Sodium hydroxide is insoluble in ether and other non-polar solvents. Similar to the hydration of sulfuric acid, dissolution of solid sodium hydroxide in water is a highly exothermic reaction [17] where a large amount of heat is liberated, posing a threat to safety through the possibility of splashing. The resulting solution is usually colorless ...

  3. Propellant - Wikipedia

    en.wikipedia.org/wiki/Propellant

    Solid fuel/propellants are used in forms called grains. A grain is any individual particle of fuel/propellant regardless of the size or shape. The shape and size of a grain determines the burn time, amount of gas, and rate of produced energy from the burning of the fuel and, as a consequence, thrust vs time profile.

  4. Base (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Base_(chemistry)

    Bases with only one ionizable hydroxide (OH −) ion per formula unit are called monoprotic since they can accept one proton (H +). Bases with more than one OH- per formula unit are polyprotic. [16] The number of ionizable hydroxide (OH −) ions present in one formula unit of a base is also called the acidity of the base.

  5. Neutralization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Neutralization_(chemistry)

    For example, sodium hydroxide, NaOH, is a strong base. NaOH(aq) → Na + (aq) + OH − (aq) Therefore, when a strong acid reacts with a strong base the neutralization reaction can be written as H + + OH − → H 2 O. For example, in the reaction between hydrochloric acid and sodium hydroxide the sodium and chloride ions, Na + and Cl − take ...

  6. Lye - Wikipedia

    en.wikipedia.org/wiki/Lye

    Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).

    North Korea's Hwasong-18 intercontinental ballistic missile (ICBM), launched for the second time on Wednesday, uses solid-fuel technology, giving it the capability to launch with little preparation.

  8. Aqueous solution - Wikipedia

    en.wikipedia.org/wiki/Aqueous_solution

    Sodium hydroxide (NaOH) is an Arrhenius base because it dissociates the hydroxide ion when it is dissolved in water. [3] Aqueous solutions may contain, especially in the alkaline zone or subjected to radiolysis, hydrated atomic hydrogen and hydrated electrons. [citation needed]

  9. Solid fuel - Wikipedia

    en.wikipedia.org/wiki/Solid_fuel

    Solid fuels have been used throughout human history to create fire [2] and solid fuel is still in widespread use throughout the world in the present day. [3] [4] Solid fuel from biomass is regarded as a renewable energy source which can contribute to climate change mitigation efforts. Solid fuel from fossil fuels (i.e. coal) is not a renewable ...
