　View Summary

We measured pH values of seawater collected at coast of Wakayama prefecture in the present study. By referring to these pH values of seawater, pH behaviors at brackish-water regions of Wakagawa River and Kinokawa River were investigated. As a result, it becomes clear that pH values of brackish-water are mostly controlled by tide.

Quantification of chloride ions in brackish water and its application to inquiry learning in high school

Noriyoshi Kimura, Koki Ogawa, Fumiko Nakamura （Part： Lead author,　Corresponding author )

Bulletin of the Faculty of Education, Wakayama University. Natural science ( 和歌山大学教育学部 )  74   17 - 25   2024.02  [Refereed]

　View Summary

We tried to measure quantity of chloride ion in sea water by Mohr method at estuaries of the Wakagawa River and Kinokawa River. From these results, it is clear that the concentrations of chloride ion at estuaries are correlated with ebb and flow of the tide. The maximum of concentrations of chloride ion observed at estuary of the Wakagawa River is 18,560 mg L-1, and this value is similar to ca. 19,000 mg L-1 in the Kuroshio Current. On the other hand, the concentrations of chloride ion observed at estuary of the Kinokawa River are almost smaller than those at estuary of the Wakagawa River. This result is attributable to larger amount of running water in river. Finally, these experiments were applied into practice in high school.

Bulletin of the Faculty of Education, Wakayama University. Natural science ( Faculty of Education, Wakayama University )  73   7 - 10   2023.02  [Refereed]

　View Summary

In the present study, we measured dissolved oxygen (DO)and chemical oxygen demand (COD) in tap water, ponds, and river water in our life. The obtained data showed the difference values in various places. It is notable that the values of COD of the pond in site of Wakayama University were markedly increased from 2009 to 2022. On the other hand, the evaluated DO and COD values of the Kishigawa River and the Hikata River in Wakayama Prefecture remained unchanged for long periods of time. Therefore, these values are considered to environmental indicators. It is expected that the studies of DO and COD measurements can be applied in chemistry class and themed research of high school.

Some comments on the practical science education

Wataru Ishizuka, Noriyoshi Kimura, Hideki Takasu, Kunihiko Hisatomi

Bulletin of the Faculty of Education, Wakayama University. Educational science ( Faculty of Education, Wakayama University )  58   75 - 78   2008.02

　View Summary

We report on our unique education program for science teacher that includes many familiar environments or simple experiments. It has been already proved that the practical science education is very effective to make students be interested in the class. In elementary schools and junior high schools, however, it has become difficult to perform practical observations or experiments in a science class. One of the reasons is the lack of teachers' skills. In addition, it must be stressed that scientific knowledge is crucially important for science teachers. It is desirable that students learn the teaching skills at schools, as well as study the science theories hidden behind the easily discernible phenomenon at the university. These two factors, theory and practice, must be balanced to train good science teachers.

Metal valence and spin structures in 1-D Ni-Pd mixed-metal complexes, [Ni1-xPdxBr(chxn)2](NO3)2 (0.00≤x≤1.00), studied by 13C NMR and ESR measurements

Aki Josako, Noriyoshi Kimura （Part： Last author,　Corresponding author )

Bulletin of the Faculty of Education, Wakayama University. Natural science ( Faculty of Education, Wakayama University )  58   31 - 34   2008.02

　View Summary

13C solid-state NMR and ESR spectra were observed in [Ni1-xPdxBr(chxn)2] (NO3)2 (0.00<x<1.00; chxn: 1R, 2R-diamonocyclohexane), where the antiferromagnetically coupled paramagnetic-Br-Ni3+-Br-Ni3+-Br- chains are formed at x= 0.00, while the mixed-valence-Br-Pd2+-Br-Pd4+-Br- state is formed at x= 1.00. The 13C NMR signals at Cα coordinating to Ni atoms in mixed-metal complexes afforded the marked decrease of intensity with increasing x from 0.00. This result seems to be attributed to the effect of the strong spin fluctuation on paramagnetic Ni3+ sites, and was supported by ESR spectrum measurement.

Bulletin of the Faculty of Education, Wakayama University. Natural science ( Faculty of Education, Wakayama University )  56   17 - 19   2006.02

　View Summary

The carbon-13 NMR chemical shifts for thirteen 2-substituted fluorenes have been measured in chloroform-d at 100MHz. The substituent induced chemical shifts (SCS) for C11, showed an inversed trend where as SCS for C7 exhibited normal trend in the sense of the substituent electronic effect. These phenomena are as good as those observed for the SCS of the corresponding carbons of the 4-substituted biphenyls. The π electrons of the remote benzene ring were polarized by the charge of the substituted phenyl moiety.

Bulletin of the Faculty of Education, Wakayama University. Natural science ( Faculty of Education, Wakayama University )  56   31 - 33   2006.02

　View Summary

We performed the DSC, X-ray and UV-Vis spectrum measurements on [Pt(en)2] [PtBr2(en)2] (ClO4)4 in which a modification was reported by crystallizing from aqueous solution below room temperature. A metastable phase crystallizing below room temperature showed a different phase transition with thermochromism at ca. 380K to the stable form. The obtained X-ray powder patterns confirmed that the phase transition at 380K was transformation into the stable form.

Bulletin of the Faculty of Education, Wakayama University. Natural science ( Faculty of Education, Wakayama University )  56   27 - 29   2006.02

　View Summary

We measured the temperature dependences of 2H NMR spectra and 1H spin-lattice relaxation time (T1) in [Pt(en)2] [PtX2(en)2] (SO4)2・6H2O (X: Cl and I). The obtained 2H NMR spectra and 1H T1 at T>250K were attributable to the 180°flip motion of the water molecule. The activation energy and the correlation time at infinite temperature for the 180°flip of H2O were evaluated to be Ea= 27 kJ mol-1 and τ0=1.0×10-13 s, respectively. These results suggest that the network of the hydrogen bond through H2O molecules is strongly linked in the crystal.

　View Summary

We measured the Raman, UV-visible and 13C CP-MAS NMR spectra of halogen-bridged 1-D Cu-Pt mixed-metal complexes, [Cu(chxn)2][PtX2(chxn)2]X4 (X: Cl and Br), consisting of -X-Cu-X-Pt-X-chain. The Raman spectra showed an overtone progression of symmetric stretching mode of Pt(IV) -Cl atoms and the fine structures with halogen isotopic splitting in Pt-Cl band below ca. 50 K. The broad carbon signals of the 13C NMR spectra observed at room temperature are attributable to strong paramagnetic effect from Cu(II) sites. This result is supported by the weak antiferromagnetic interactions between Cu(II) sites in the chain.
