Abstract
The third dissociation constant of tetracyanohydroxooxomolybdic acid, H3[MoO(OH)(CN)4], has been obtained in the temperature range 25-50�C from the pH-titration curve of its tripotassium salt against hydrochloric acid. The values of pK3 fitted an equation of Harned- Robinson type: �������������������� pK3 = (1730.72/T)-6.19+0.0308T) obtained by the method of least squares. ��� Thermodynamic quantities ΔG�, ΔH�, ΔS�, and ΔC�p for the process have been evaluated at 30�C.Keywords
