n.o.s. = not otherwise specified meaning a collective entry to which substances, mixtures, solutions or articles may be assigned if a) they are not mentioned by name in 3.2 Dangerous Goods List AND b) they exhibit chemical, physical and/or dangerous properties corresponding to the Class, classification code, packing group and the name and description of the n.o.s. entry [2]
Amsterdam-Zuidoost (Dutch pronunciation: [ˌɑmstərdɑmˈzœyt.oːst]; "Amsterdam-Southeast") is a borough (stadsdeel) of Amsterdam, Netherlands.It consists of four residential neighborhoods—Bijlmermeer, Venserpolder, Gaasperdam and Driemond—as well as the Amstel III/Bullewijk Business Park and the Amsterdam Arena entertainment and shopping district.
The Bijlmermeer (pronounced [ˌbɛilmərˈmeːr]), or colloquially the Bijlmer (pronounced [ˈbɛilmər]), is a neighborhood in the Amsterdam-Zuidoost borough (Dutch: stadsdeel) in Amsterdam, Netherlands. The other neighborhoods in Amsterdam-Zuidoost are Gaasperdam, Bullewijk, Venserpolder and Driemond.
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 ...
The reaction between sodium hydroxide and some metals is also hazardous. Aluminium, magnesium, zinc, tin, chromium, brass and bronze all react with lye to produce hydrogen gas. Since hydrogen is flammable, mixing a large quantity of lye with aluminium could result in an explosion. Both the potassium and sodium forms are able to dissolve copper.
In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +
This sequence of reactions explains the catalytic role played by sodium hydroxide in the system and why soda lime is faster in chemical reactivity than calcium hydroxide alone. [6] The moist sodium hydroxide impregnates the surface and the porosity of calcium hydroxide grains with a high specific surface area. [7]
An aqueous solution is a solution in which the solvent is water. It is mostly shown in chemical equations by appending (aq) to the relevant chemical formula . For example, a solution of table salt , also known as sodium chloride (NaCl), in water would be represented as Na + (aq) + Cl − (aq) .
