The Electrolytic Conductivity of Zinc Sulfate and Copper Sulfate in Water at 25°¹

Glycolytic and Non-glycolytic Functions of Mycobacterium tuberculosis Fructose-1,6-bisphosphate Aldolase, an Essential Enzyme Produced by Replicating and Non-replicating Bacilli

“…In the active site of the native FBA-tb structure, electron density corresponding to the catalytic Zn 2ϩ ion was not detected. This unexpected finding is in contrast to the previous report of the substoichiometric presence of zinc ion in a native form of FBA-tb (0.5 zinc ion per protomer) purified from E. coli (18) and is most likely a consequence of competitive zinc ion sequestration by sulfate ions present in the crystallization buffer (67). A substoichiometric zinc content per subunit in class II FBP aldolases has recently been documented (68) and is as low as 0.16 zinc ion per protomer in the case of FBA from Pseudomonas aeruginosa.…”

Isopiestic determination of the osmotic and activity coefficients ofZnSO4(aq) atT= 298.15 K, and the standard potential of the electrochemical cell ZnHgx(two phase)| ZnSO4(aq)| PbSO4(s)| PbHgx(two phase)

“…Neither Masaki and Ikkatai nor Herrera et al acidified their solutions, nor did they shield their cells from light. The reported pHs of C = 4 · 10 −4 mol · dm −3 to C = 0.116 mol · dm −3 solutions of ZnSO 4 (aq) fall in the range 6.41 pH 5.71, (47) which are too high to insure that the Hg 2 SO 4 (cr)|Hg(l) electrode operates properly. Thus the e.m.f.s of Masaki and Ikkatai, and Herrera et al probably involve "mixed potentials".…”

A robotic platform for high-throughput electrochemical analysis of chalcopyrite leaching

“…† Initial testing of the platform setup included determining the geometric factor for several fabricated electrodes in certi- fied KCl (aq) conductivity standards (Sigma Aldrich), followed by accurate measurement of CuSO 4(aq) solution conductivities with <6% error (1-50 mmol dm −3 ). 22 Automated data acquisition for various IL (aq) ASV calibration plots (see ESI - Fig. S8 †) provided some ASV specific platform validation, however more complex electrochemical study was desirable, as described next.…”
