And also we obtained the co-ordination phenomenon and stability constant of the gallic acidco-ordinates with Fe3+,Fe2+,Cu2+,Mg2+,Ni2+and other ions. Data processing generated by semi-integral function, Accordingly that we obtained the designs and the total designs of the distribution of gallic acid- metal ions complexes.The order of the stability contant of gallic acid-metal complexes accords with the the classical Classic - Weilianmushi order,viz. . 目 录
