'''Thallium(I) hydroxide''', also called '''thallous hydroxide''', is a ] with the ] {{chem2|TlOH|auto=1}}. It is a ] of ], with thallium in ] +1. It is a thallium(I) ] of ]. It consists of thallium(I) ] {{chem2|Tl+}} and ] ] {{chem2|OH−}}. |
|
|
|
|
|
== Synthesis == |
|
|
Thallium(I) hydroxide is obtained from the decomposition of ] in water.<ref>{{Cite book|last=Brauer|first=Georg|title=Handbuch der Präparativen Anorganischen Chemie, Band I.|last2=Baudler|first2=Marianne|publisher=Ferdinand Enke|year=1975|isbn=3-432-02328-6|edition=3rd|location=Stuttgart|pages=883}}</ref> |
|
|
|
|
|
:{{chem2|CH3CH2OTl + H2O → TlOH + ]}} |
|
|
|
|
|
This can also be done by direct reaction of thallium with ] and ] gas. |
|
|
|
|
|
:{{chem2|4 Tl + 2 CH3CH2OH + O2 → 2 CH3CH2OTl + 2 TlOH}} |
|
|
|
|
|
Another method is the reaction between ] and ]. |
|
|
|
|
|
:{{chem2|Tl2SO4 + Ba(OH)2 → 2 TlOH + ]}} |
|
|
|
|
|
== Properties == |
|
|
Thallium(I) hydroxide is a strong ]; it ] to ](I) ], {{chem2|Tl+}}, and ] ], {{chem2|OH−}}, except in strongly ]. {{chem2|Tl+}} cation resembles an ] cation, such as {{chem2|]+}}, {{chem2|]+}} or {{chem2|]+}}. |
