The solvent is water. Pure water has a freezing point of 0 degrees Celsius. How come, in this problem, the addition of solute results in an elevation of the freezing point from 0 to 0.46 degrees C? Is this possible? Or is this question just flawed?

    $\begingroup$ I would assume that this is supposed to be $-0.46\ ^{\circ}\mathrm{C}$... $\endgroup$ – Zhe Feb 24 '17 at 16:06
  • $\begingroup$ My thought as well. $\endgroup$ – Ivan Neretin Feb 24 '17 at 16:07
  • $\begingroup$ Adding deuterium oxide would raise the freezing point. $\endgroup$ – MaxW Feb 24 '17 at 16:47
  • $\begingroup$ I see no problem here. It's not a salt and it doesn't lower melting point but on contrary... $\endgroup$ – Mithoron Feb 24 '17 at 16:48
