Product description
- The surface tension of aqueous solutions of n-butyric acid in the region of low concentrations obeys the empirical Shishkovsky equation with coefficients A=0.051 mol/l and B=0.178 at 18 °C (the surface tension of water at this temperature is 72.6 mN/m). Using this equation, calculate the surface activity (-dσ/dС) at С→0 analytically
