    As a result, they resided at An Duong's court until Zhong Shi discovered the secrets and strategies of King An Dương. [21] Meanwhile, King An Duong mistreated Cao Lỗ, and he left. [22] Zhong Shi had Mỵ Châu showed him the crossbow, at which point he secretly changed its trigger, neutralizing its special powers and rendering it useless. [20]

    en.wikipedia.org/wiki/Sodium_hydroxide

    The only hydrates with stable melting points are NaOH·H 2 O (65.10 °C) and NaOH·3.5H 2 O (15.38 °C). The other hydrates, except the metastable ones NaOH·3H 2 O and NaOH·4H 2 O (β) can be crystallized from solutions of the proper composition, as listed above. However, solutions of NaOH can be easily supercooled by many degrees, which ...

    en.wikipedia.org/wiki/Titration_curve

    A typical titration curve of a diprotic acid, oxalic acid, titrated with a strong base, sodium hydroxide.Both equivalence points are visible. Titrations are often recorded on graphs called titration curves, which generally contain the volume of the titrant as the independent variable and the pH of the solution as the dependent variable (because it changes depending on the composition of the ...

    en.wikipedia.org/wiki/Hydroxide

    The hydroxide ion appears to rotate freely in crystals of the heavier alkali metal hydroxides at higher temperatures so as to present itself as a spherical ion, with an effective ionic radius of about 153 pm. [38] Thus, the high-temperature forms of KOH and NaOH have the sodium chloride structure, [39] which gradually freezes in a ...

    CH 3 COOH + NaOH → CH 3 COONa + H 2 O. To manufacture anhydrous sodium acetate industrially, the Niacet Process is used. Sodium metal ingots are extruded through a die to form a ribbon of sodium metal, usually under an inert gas atmosphere such as N 2 then immersed in anhydrous acetic acid. 2 CH 3 COOH + 2 Na →2 CH 3 COONa + H 2.
