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.

Copper(II) hydroxide is the hydroxide of copper with the chemical formula of Cu(OH) 2. It is a pale greenish blue or bluish green solid. It is a pale greenish blue or bluish green solid. Some forms of copper(II) hydroxide are sold as "stabilized" copper(II) hydroxide, although they likely consist of a mixture of copper(II) carbonate and hydroxide.
Iron dissolved in groundwater is in the reduced iron II form. If this groundwater comes in contact with oxygen at the surface, e.g. in natural springs, iron II is oxidised to iron III and forms insoluble hydroxides in water. [7] The natural analogue of iron(II) hydroxide compound is the very rare mineral amakinite, (Fe,Mg)(OH) 2. [8] [9]
Nickel(II) hydroxide is the inorganic compound with the formula Ni(OH) 2. It is a lime-green solid that dissolves with decomposition in ammonia and amines and is attacked by acids. It is electroactive, being converted to the Ni(III) oxy-hydroxide , leading to widespread applications in rechargeable batteries .
Cobalt(II) hydroxide or cobaltous hydroxide is the inorganic compound with the formula Co(OH) 2, consisting of divalent cobalt cations Co 2+ and hydroxide anions OH −. The pure compound, often called the "beta form" (β-Co(OH) 2) is a pink solid insoluble in water. [2] [3]
The Mn(II) centers are bonded to six hydroxide ligands. Each hydroxide ligand bridges to three Mn(II) sites. The O-H bonds are perpendicular to the planes defined by the oxygen atoms, projecting above and below these layers. [2] Manganese(II) hydroxide precipitates as a solid when an alkali metal hydroxide is added to an aqueous solution of Mn ...
The solubility in water of the other hydroxides in this group increases with increasing atomic number. [18] Magnesium hydroxide Mg(OH) 2 is a strong base (up to the limit of its solubility, which is very low in pure water), as are the hydroxides of the heavier alkaline earths: calcium hydroxide , strontium hydroxide , and barium hydroxide .
