146. Solving a chemistry problem

Product description

• Calculate the adsorption of valeric acid at the interface between aqueous solution and air (at T = 293 K) and the solution concentration

C = 0.0206 kmol / m 3, if the dependence of the surface tension of the solution on the concentration is represented by the following experimental data:

C, kmol / m 3 0.0 0.0103 0.0206 0.0683 0.2049
