List of desiccants: [1]. Activated alumina; Aerogel; Benzophenone (as anion); Bentonite clay; Calcium chloride; Calcium hydride; Calcium oxide; Calcium sulfate ...
This hinders the aluminium oxidation by the protons of water and reduces the hydrogen evolution rate by a factor of 10. [8] Lithium aluminate also finds its use as an inert electrolyte support material in molten carbonate fuel cells, where the electrolyte may be a mixture of lithium carbonate, potassium carbonate, and sodium carbonate.

A grinding wheel is used as a cutting tool as a cathode and the workpiece is an anode. During the process, electrolytic fluid, typically sodium nitrate, [5] is pumped into the space between the workpiece and the grinding wheel. Other electrolytes used include sodium hydroxide, sodium carbonate, and sodium chloride. [6]
Aluminium (British and IUPAC spellings) or aluminum (North American spelling) combines characteristics of pre- and post-transition metals. Since it has few available electrons for metallic bonding, like its heavier group 13 congeners, it has the characteristic physical properties of a post-transition metal, with longer-than-expected interatomic ...
Hard water represents a multifold issue. It is of great interest to remove these ions, thus softening the water. This procedure can be done using reagents such as calcium hydroxide, sodium carbonate or sodium phosphate. A more common method is to use ion-exchange aluminosilicates or ion-exchange resins that trap Ca 2+ and Mg 2+ and liberate Na ...
Salt/common salt – a mineral, sodium chloride, NaCl, formed by evaporating seawater (impure form). Salt of tartar – potassium carbonate; also called potash. Salt of hartshorn/sal volatile – ammonium carbonate formed by distilling bones and horns. Tin salt – hydrated stannous chloride; see also spiritus fumans, another chloride of tin.
It does not react with aqueous, solid, or molten sodium or potassium hydroxide. It does however, react with sodium or potassium cyanide under alkaline conditions when oxygen is present to form soluble complexes. [10] Common oxidation states of gold include +1 (gold(I) or
For example, carbonate green rust can be prepared by mixing solutions of iron(II) sulfate FeSO 4 and sodium hydroxide; then adding sufficient amount of sodium carbonate Na 2 CO 3 solution, followed by the air oxidation step. [36] Sulfate green rust can be obtained by mixing solutions of FeCl 2 ·4 H 2 O and NaOH to precipitate Fe(OH) 2 then ...
