When a chemical is dissolved in a liquid, the freezing temperature of that liquid is slightly lowered as a result. One example of this is that salt water freezes at a lower temperature than pure water. The following table shows the freezing temperatures of several liquids. Liquid Temperature
Water 0.0°C
Acetic acid
(vinegar) 17.0°C
Ethanol
(alcohol) -114.7
Of the choices listed, a liquid with a freezing point of -1°C would most likely be made of
A.
something dissolved in water.
B.
pure ethanol.
C.
something dissolved in acetic acid.
D.
something dissolved in ethanol.
