Product description
5.6. Using the constants of the Shishkovsky equation: a = 21.12*10–3, b = 42.0, calculate the surface tension for aqueous solutions of isoamyl alcohol at 273 K for the following concentrations (kmol/m3): 0.005; 0.020; 0.05; 0.100 and plot a graph in coordinates σ = f(C); take the surface tension of water equal to 72.75*10–3 N/m.
