ANSWER

Provide a baseline for comparison to isolate the tested effect. Control groups eliminate alternative explanations by providing a reference point without the experimental treatment.

A thin, nonreactive polymer film separates two aqueous compartments containing KCl at the same concentration (0.10 M) but different temperatures: side 1 at 298 K and side 2 at 310 K. The film is permeable to ions and water, and no external voltage is applied. A student predicts a sustained net electric current will flow from the hot side to the cold side solely due to the temperature difference. Assuming both compartments remain electrically neutral and that diffusion is driven by chemical potential gradients, which evaluation is most consistent with these principles? Given: For an ideal solute, μ=μ∘+RTln⁡a\mu = \mu^\circ + RT\ln a; for dilute solutions, a≈a\approx concentration.
