Homework Answers
2) The conductivity( specific conductance ) of a solution is defined as the conductance of 1 unit volume of solution. Thus as the concentration of solution increases, the number of ions present in the solution increases, thus the specific conductance/ conductivity increases.
Thus 0.030M NaCl has more number of ions/unit volume , thus has double conductivity than 0.015M NaCl.
3) 0.030M Na2SO4 has more number of ions (3 ions for formula) than 0.030M NaCl (2 ions for formula)
Thus na2SO4 has greater conductivity than NaCl.

Select the single best answer. Explain in terms of intermolecular forces the following: Why NaCl has a higher melting point than 12 Because NaCl is soluble in water, and I, is not. Because NaCl is an ionic compound, and the ion-ion attractions are much stronger than the dispersion forces between the I, molecules. Because NaCl is a solid, and I, is a liquid. Because NaCl can form hydrogen bonds, and I cannot.
