The amount of ammonia in ammonium salts can be estimated quantitatively by distillation of the salts with sodium (NaOH) or potassium hydroxide (KOH), the ammonia evolved being absorbed in a known volume of standard sulfuric acid and the excess of acid then determined volumetrically; or the ammonia may be absorbed in hydrochloric acid and the ...
Sodium hydroxide, also known as lye and caustic soda, [1] [2] is an inorganic compound with the formula NaOH. It is a white solid ionic compound consisting of sodium cations Na + and hydroxide anions OH −. Sodium hydroxide is a highly corrosive base and alkali that decomposes lipids and proteins at ambient temperatures and may cause severe ...
It can be prepared by reacting a sodium-containing base such as sodium hydroxide with iodic acid, for example: HIO 3 + NaOH → NaIO 3 + H 2 O. It can also be prepared by adding iodine to a hot, concentrated solution of sodium hydroxide or sodium carbonate: 3 I 2 + 6 NaOH → NaIO 3 + 5 NaI + 3 H 2 O
Sodium orthovanadate is produced by dissolving vanadium(V) oxide in a solution of sodium hydroxide: V 2 O 5 + 6 NaOH → 2 Na 3 VO 4 + 3 H 2 O. The salt features tetrahedral VO 3− 4 anion centers linked to octahedral Na + cation sites. [3]
Sodium metasilicate is the chemical substance with formula Na 2 SiO 3, which is the main component of commercial sodium silicate solutions. It is an ionic compound consisting of sodium cations Na +
A related, updated procedure uses sodium methoxide instead of sodium hydroxide: [3] NaOCH 3 + HOC 6 H 5 → NaOC 6 H 5 + HOCH 3. Sodium phenoxide can also be produced by the "alkaline fusion" of benzenesulfonic acid, whereby the sulfonate groups are displaced by hydroxide: C 6 H 5 SO 3 Na + 2 NaOH → C 6 H 5 OH + Na 2 SO 3
