Any salt can be used for the \(\ce{Zn}\)-electrode. Brainstorm from class. Question: Classify the following substances as strong electrolytes . Electrolytes are chemicals that break into ions in water. \(\mathrm{Zn_{\large{(s)}} \rightarrow Zn^{2+}_{\large{(aq)}} + 2 e^-}\). As the solution approaches zero concentration, virtually all of the \(MX_{(aq)}\) becomes dissociated, and the conductivity reaches its limiting value. These weak electrolytes, like the intermediate ones, will be totally dissociated at the limit of zero concentration; if the scale of the weak-electrolyte plot (blue) shown above were magnified by many orders of magnitude, the curve would resemble that for the intermediate electrolyte above it, and a value for could be found by extrapolation. 11.2: Ions in Solution (Electrolytes) - Chemistry LibreTexts The non-ideality of electrolytic solutions is also reflected in their colligative properties, especially freezing-point depression and osmotic pressure. Strong electrolytes completely ionize when dissolved, and no neutral molecules are formed in solution. These studies revealed that the equivalent conductivities of electrolytes all diminish with concentration (or more accurately, with the square root of the concentration), but they do so in several distinct ways that are distinguished by their behaviors at very small concentrations. ), but for strong and intermediate electrolytes, one can extrapolate a series of observations to zero. For pure water, \(\ce{[H2O]}\) is a constant (1000/18 = 55.6 M), and we often use the ion product, Kw, for water, \(\mathrm{\mathit K_w = \mathit K [H_2O] [H^+] [OH^-]}\). a high NH3 yield rate of ~70 g h-1 mgcat.-1 and a high Faradaic efficiency of ~26% at -0.5 V vs. RHE in an aqueous electrolyte.
