Question

At which temperature does a concen-
trated aqueous solution of sodium
chloride begin to boil?
A 96 °C
B 99 °C
D 104 °C
с
100 °C

Answer 1

Answer:

108.7 °C

Solutions of sodium chloride have very different properties from pure water. The freezing point is −21.12 °C (−6.02 °F) for 23.31 wt% of salt, and the boiling point of saturated salt solution is near 108.7 °C (227.7 °F).
