DESCRIPTION
0722. Solving a chemistry problem
18. The specific electrical conductivity of an extremely dilute solution of ethylamine (C2H5NH3OH) is 1.312*10-3 S/cm at 298 K, and the molar electrical conductivity of the same solution is 232.6 S*cm2/mol. Calculate the molar electrical conductivity at dilution V = 16 dm3/mol. Also determine the degree of dissociation, the concentration of hydroxyl ions, and the dissociation constant.
Answer:
2.099*10-2 Sm*cm2/mol; 9.02 *10-5; 5.64 * 10-6 mol/dm3; 8.145 * 10-9 mol/dm3.
