Determination of hydrogen ion concentrations in phosphate and borate mixtures by means of the quinhydrone electrodes.
THE application of the quinhydrone electrode (or the quinoquinhydrone electrode or the hydroquinhydrone electrode) as substitute for the hydrogen electrode for the determination of PH is based on the fact that the values of the potentials between one of these electrodes and the hydrogen electrode vary but very little if the electrolytes of the two electrodes of the chain examined are identical....
متن کاملFc–ssDNA conjugate: electrochemical properties in a borate buffer and adsorption on gold electrode surfaces
By using an electroactive species such as ferrocene (Fc), the electrochemical properties of bioorganic molecules were indirectly made accessible. 50-Fc-NH-ssDNAs have a redox potential of 430–440 mV (vs. AgjAgCl) in a borate buffer (pH 9), which is characteristic of ferrocene/ferrocenium (Fc/Fcþ) substituted by an amide group. The diffusion coefficient of Fc–ssDNA conjugates in a buffer solutio...

15 صفحه اول3-Methylanilinium hydrogen phthalate
The asymmetric unit of the title salt, C(7)H(10)N(+)·C(8)H(5)O(4) (-), consists of two 3-methyl-phenyl-ammonium cations and two hydrogen phthalate anions. There are strong intra-molecular O-H⋯O hydrogen bonds in the virtually planar (r.m.s. deviations = 0.054 Å) phthalate anions. In the crystal, the cations and anions are connected via an extensive sytem of N-H⋯O hydrogen bonds into a corrugate...
متن کامل4-Bromoanilinium hydrogen phthalate
In the anion of the title compound, C(6)H(7)BrN(+)·C(8)H(5)O(4) (-), the dihedral angles formed by the benzene ring and the mean planes of the -COOH and -COO(-) groups are 20.6 (3) and 83.2 (3)°, respectively. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds connect the cations and anions, forming a two-dimensional network parallel to (001).
