Spectrophotometric investigation of titanyl oxalate-morin complex in 50% v/v ethanol
Spektrofotometrijsko ispitivanje kompleksa titanil oksalat-morin u 50% v/v etanolu
Apstrakt
The composition of the titanyl oksalat-morin complex was determined by spectrophotometric method of variations of equimolar solutions and by the mole ratios method. The investigation of the composition and the concentration stability constant of the complex were carried out in a 50% V/V ethanol. It was found that titanyl oxalate ion and morin form 1:2 complex. The concentration stability constant of the complex, logβ2 was calculated for the pH=6,0 (5.83), pH=7,0 (6.40) andpH=8,0 (7.35).
Sastav titanil oksalat-morin kompleksa određenje spektrofotometrijskom metodom varijacija ekvimolarnih rastvora i metodom molarnih odnosa. Ispitivanje sastava i određivanje koncentracionih konstanti stabilnosti ovog kompleksa vršeni su u 50% V/V etanolu. Nađeno je da se formira kompleks TiO(C2O4)22-: morin = 1:2. Određene su koncentracione konstante stabilnosti kompleksa: log β2 = 5,83 (pH = 6,0), log β2 =6,40 (pH = 7,0) i log β2 = 7,35 (pH =8,0).
