A 0.10 Maqueous solution of sodium sulfate, Na2S04, is a better conductor of electricity than a 0.10 Maqueous solution of sodium chloride, NaCl. Which of the following best explains this observation? Na2S04 is more soluble in water than NaCI A is. Na2S04 has a higher molar mass than NaCl В has. To prepare a given volume of 0.10 M solution, the mass of Na2S04 needed is more than twice the mass of NaCl needed. More moles of ions are present in a given D volume of 0.10 MNa2S04 than in the same volume of 0.10 M NaCl. The degree of dissociation of Na2S04 in solution is significantly greater than that of NaCl.

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
