Silver mole relationships

We see that there is a simple relationship between the weight of copper dissolved and the weight of silver deposited. One mole of copper dissolves in the right beaker for every two moles of silver deposited in the left beaker. Copper ions, Cu+YaqJ, are formed in the right beaker from... 

Silver acetylide decomposition was studied [679] by X-ray diffraction and microscopic measurements and, although the a—time relationship was not established, comparisons of intensities of diffraction lines enabled the value of E to be estimated (170 kj mole 1). The rate-limiting step is believed to involve electron transfer and explosive properties of this compound are attributed to accumulation of solid products which catalyze the decomposition (rather than to thermal deflagration). 

From this mole-gram relationship come the units of molar mass, grams/mole. For example, the molar mass of silver nitrate (AgN03) is 170 grams/mole. 

Flory s mathematical relationships for the free energy change that occurs when a solute is mixed with a solvent for the solution phase and the solid phase have been discussed as they apply to collagen assembly by Silver (1987). The free energy of mixing of solute and solvent per mole of molecules is equivalent to the change in chemical potential of a desired state (p)... 

Each mole of electrons that passes through the cell arises from the oxidation of j mol of Zn(s) (because each Zn atom gives up two electrons) and reduces 1 mol of silver ions. From the molar masses of silver and zinc, we calculate that 65.38/2 = 32.69 g of zinc is dissolved at the anode and 107.87 g of silver is deposited at the cathode. The same relationships hold if the cell is operated as an electrolytic cell, but in that case silver is dissolved and zinc is deposited. 

The importance of the basic amino acids has been further substantiated by evaluations of the relationship between a denatured protein s amino acid mole percentages and its ability to stain with silver. The best correlations were achieved when a comparison was made between the slope of the linear portion of a denatured protein s staining curve and the protein s mole percentages of the basic amino acids, histidine and lysine ( ). A similar correlation was observed by Dion and Pomenti(4 ). Dion and Pomenti suggested that this correlation may be due to an interaction between lysine and glutaraldehyde, which was used in their stain protocol. The bound glutaraldehyde could supply aldehyde groups to facilitate the reduction of ionic silver. While this mechanism may play a role in... 

In Eqs. (122) and (123), M(Hg) is an alkali metal amalgam electrode, MX the solvated halide of the alkali metal M at concentration c in a solvent S, and AgX(s)/Ag(s) a silver halide-silver electrode. Equation (124) is the general expression for the electromotive force " of a galvanic cell without liquid junction in which an arbitrary cell reaction 0)1 Yi + 0)2Y2 + coiYi + , takes place between k components in v phases. In Eq. (124) n is the number of moles of electrons transported during this process from the anode to the cathode through the outer circuit, F the Faraday number, and the chemical potential of component Yi in phase p. Cells with liquid junctions require the electromotive force E in Eq. (124) to be replaced by the quantity E — Ej), where Ey> is the diffusion potential due to the liquid junction. The standard potential E° for the cell investigated by Eq. (122) is given by the relationship...
