The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
Titanium nitride (TiN) is a refractory solid exhibiting extreme hardness, thermal/electrical conductivity, and a high melting point. [13] TiN has a hardness equivalent to sapphire and carborundum (9.0 on the Mohs scale), [14] and is often used to coat cutting tools, such as drill bits. [15]
Tin(II) oxide burning. Blue-black SnO can be produced by heating the tin(II) oxide hydrate, SnO·xH 2 O (x<1) precipitated when a tin(II) salt is reacted with an alkali hydroxide such as NaOH. [4] Metastable, red SnO can be prepared by gentle heating of the precipitate produced by the action of aqueous ammonia on a tin(II) salt. [4]
Titanium(II) sulfide (TiS) is an inorganic chemical compound of titanium and sulfur. A meteorite, Yamato 691 , contains tiny flecks of this compound, making it a new mineral called wassonite . [ 2 ]
