2015年8月9日 · Most pH electrode storage solutions are 4 M KCl with a pH about 4. The solution you have should be fine if you can change the internal solution on a monthly basis (more often if you use it continuously). The internal solution is also saturated with silver chloride.

2019年8月29日 · We want to store non-toxic (non-cyanide) gold solution for electroplating in a small (10-20ml) transparent container that has an inbuilt, permanent electrode for the plating process: But I can't find anywhere to buy such a thing and I don't know if it has a specific name.

2022年1月21日 · Because as such the solution remains neutral. But the more charge carriers in the solution, the higher the rate until either rate of oxidation or reduction limit the overall rate (depends on the electrodes' surface, the applied electrical potential, etc.). $\endgroup$ –

2016年9月25日 · If the copper ions in solution, which are to be reduced, come in contact with the Zn electrode then the copper ions would plate on the Zn electrode. So a membrane of some sort must be used as a barrier which keeps the copper ions away from the Zn electrode but still allows anions to flow through the barrier.

2022年10月26日 · Edit : The potential of an electrode dipping in pure water is not defined if the "solution" is totally pure water. Another way of saying it is to say that the potential is infinite if there is absolutely no ion of this electrode in solution. But it is practically impossible to get a solution with zero ion of the corresponding metal in solution.

2017年4月8日 · The glass electrode is an ion-selective electrode for $\ce{H+}$ made of amorphous silicate glass, which consists of connected $\ce{SiO4}$ tetrahedra. Presumably, no special preparative techniques are required for the glass, and the depth of the hydrated gel layer is mediated by the strength and range of the intermolecular interactions between ...

2014年6月4日 · However, there is activation energy in nucleating a new phase ($\ce{Cu}$ metal). Thus we will get super-saturated: Conceptually, the "concentration" of $\ce{Cu}$ metal at the Zn electrode exceeds the concentration of $\ce{Cu}$ metal at the copper electrode before the $\ce{Cu}$ phase appears! However, once $\ce{Cu}$ plating begins, the voltage ...

2018年1月17日 · The potentials depend on the form of the compounds. It is true that in solution $\ce{Pb^{2+} (aq) + 2e^- -> Pb (s)} $ is -0.126 V. But in the case of a battery we have: $\ce{PbSO4 (s) + 2e^- -> Pb (s) + SO4^{2-} (aq)}$ And in this case the $\ce{Pb^{2+}}$ is in solid form and the potential is -0.356 V.

2020年5月3日 · The initial solution contains $\ce{Fe^{2+}}$ and $\ce{Cl^-}$ ions. During charging, the $\ce{Fe^{2+}}$ ions are moving to the negative electrode made of Iron, where they are discharged and transformed into metallic Fe. Simultaneously, the $\ce{Cl^-}$ ions are moving to the positive electrode made
