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 −.
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 ...
In general, as temperature decreases from 25 °C to 5 °C the pH of a tris buffer will increase an average of 0.03 units per degree. As temperature rises from 25 °C to 37 °C, the pH of a tris buffer will decrease an average of 0.025 units per degree.

The room-temperature form of NaOH has the thallium iodide structure. LiOH, however, has a layered structure, made up of tetrahedral Li(OH) 4 and (OH)Li 4 units. [39] This is consistent with the weakly basic character of LiOH in solution, indicating that the Li–OH bond has much covalent character.
Vanadates exhibit a variety of biological activities, in part because they serve as structural mimics of phosphates. [6] [7] It acts as a competitive inhibitor of ATPases, alkaline and acid phosphatases, and protein-phosphotyrosine phosphatases, [8] and its inhibitory effects can be reversed by dilution or the addition of ethylenediaminetetraacetic acid (EDTA).
To prepare 1 liter of TSB, the following ingredients are dissolved under gentle heat. Adjustments to pH should be made using 1N HCl or 1N NaOH to reach a final target pH of 7.3 ± 0.2 at 25°C. The solution is then autoclaved for 15 minutes at 121°C. [3] Tryptic Soy Agar contains per liter: 17 g pancreatic digest of casein; 3 g peptic digest ...
