Diffusion of Silver Nitrate in Concentrated Aqueous Solutions

Ionic Mass Transfer Associated with Dendritic Growth of Electrodeposited Silver in AgNO3 Solution

“…This is illustrated in Fig. 4 and 5 are 1.83 x 10 -5 and 1.57 x 10 -5 cm2/s, respectively, in good agreement with the reported value of 1.26 x 10 -5 cm2/s (19,20). The diffusivity of Ag § ion in the electrolyte can be estimated from these experimental data.…”

Verification and Analysis of Transference Number Measurements by the Galvanostatic Polarization Method

“…We next need to obtain values of D and dU/d ln c. For this purpose, literature data on the salt diffusion coefficient, [17][18][19][20][21] concentration cell OCPs, 22 and solution density 17,18,[23][24][25][26] at 25ЊC were fit to analytic functions of concentration, c, as described in the introduction. The density () is required because different concentration scales (molality or molarity) were used in different studies.…”

Interfacial tension controlled fusion of individual femtolitre droplets and triggering of confined chemical reactions on demand

“…The fact that the AgCl(s) product was located on only one side of the fused droplet indicates the precipitation rate was faster than any mixing time scales in the droplet. Product formation was considerably faster than the estimated diffusive mixing time, which would be on the order of 10 ms, using t mix ¼ hx 2 i/2D in a 5 mm diameter product droplet as an estimate, and using the published diffusion coefficient for 2 M AgNO 3 (aq) of about 10 3 mm 2 s À1 42. To obtain a clearer picture of the relative roles of convective versus diffusive mixing triggered by droplet fusion, we measured the timedependent change in fluorescence intensity from a droplet containing 50 nm diameter fluorescent polymer microspheres (FS02F/9290, Bangs Laboratories) in phosphate buffer as it merged with a droplet containing only buffer solution, shown in Fig.3.…”
