The solvent extraction of hydrohalogenic acids and thiocyanic acid (HX) in 1 mol dm<SUP>−3</SUP> electrolyte solutions with trioctylphosphine oxide (E) has been studied at 25 °C. The extraction constant, <I>K</I><SUB>ex<SUB>1</SUB></SUB>=[HXE]<SUB>org</SUB>[H<SUP>+</SUP>]<SUP>−1</SUP>[X<SUP>−</SUP>]<SUP>−1</SUP>][E]<SUB>org</SUB><SUP>−1</SUP>, for thiocyanic acid was found to be 10<SUP>2.5</SUP>, while <I>K</I><SUB>ex<SUB>2</SUB></SUB>=[HXE<SUB>2</SUB>]<SUB>org</SUB>[H<SUP>+</SUP>]<SUP>−1</SUP>[X<SUP>−</SUP>]<SUP>−1</SUP>[E]<SUB>org</SUB><SUP>−2</SUP> for hydrobromic and hydroiodic acids were found to be 10<SUP>0.34</SUP> and 10<SUP>1.78</SUP> respectively.
