This paper reports the light absorption (between 400--800 mμ) of pyrocate-chol-ferric iron solutions in the range of pH 2--12, and the complexes found bymeans of Job's continuous variation method with spectrophotometer (Unicam,S. P. 500). It is found that there are five complexes in the solutions studied,among which two (I, III) have not yet been reported previously. The resultsare summaried as follows: In solutions of pH intermediate those given above, there are mixtures of thetwo adjacent complexes. For example, in solutions of pH 2.5--3.5 two com-plexes, I and II, exist side by side. The differences between complexes III andV probably lie in differences in electrical charge and (or) structure of theanions. The properties of three known complexes (II, IV, V) confirm those foundby previous authors with slight variations in pH ranges. Fluoride ions can not bleach the color formed in solutions containing ferricions and pyrocatechol of pH 4.2--10. In other words, these complexes are morestable than ferricfluoride complex. Solutions of pH 2--4 do fade as fluoridesolutions are added. However, these colors change gradually with time and isnever so stable as other known reagents for fluoride determination, such asferron-ferric or resacetophenone-ferric reagents. The sensitivity of thepresent reagent towards fluoride is also inferior to that of the reagents justmentioned.

It was found that molybdenum in molybdenum-thiocyanate complexes ispentavalent. In aqueous-acetone solutions, when the concentration of hydroch-Ioric acid lies between 0.9 and 2.5 N only one colored complex is formed,which imparts a cherry red color to the solution. In 25% or 50% acetone solution, the ratio of Mo(Ⅴ): CNS~- of this com-plex is 1: 4, and is positively charged (by means of migration method). Hencethe composition of this cherry red complex is [Mo (CNS)_4]~+. In addition, acolorless complex, (MoCNS)~(4+), is also formed. At lower thiocyanate concen-tration, a yellow-colored complex is formed in 75% acetone solution and theratio of Mo(Ⅴ): CNS~- is 1: 1. In more concentrated molybdenum solutions,the complex [Mo (CNS)_4]~+ is formed, which gradually changes to Mo (CNS)_5after half an hour standing. The complexes [Mo (CNS)_4]~+ and Mo (CNS)_5show maximum absorption at 465mμ and 507mμ respectively. The lowest concentration of potassium thiocyanate required for converting2×10~(-4) M Mo(Ⅴ) to [Mo (CNS)_4]~+ in 25% and 50% acetone solutions is 0.24 Mand 0.10 M respectively.
