Introduction
The purpose of the experiment was to investigate the boiling point of various different
increments of NaCl. Using a hot plate for heat the NaCl solution was mixed in a separate beaker
then moved to a florence flask. Where it was placed on the hot place till stabilized for a minute.
The compound used in this experiment is a grainy, white solid known as sodium chloride or salt.
Throughout the experiment different concentrations of salt water solution were used to measure
the boiling point. From what is known the boiling point of water itself is 100 ºC. Now as salt is
added to the solution it could be theorized that it may be higher. In addition sodium chloride is an
ionic compound this would make it harder to split up thus making the boiling point go up.
Hypothesis
It was hypothesized that if the concentration of salt on an increasing scale from 1 to 8 grams was
measured with a thermometer on a hot plate with distilled water then the boiling point would also
increase accordingly. Since salt, an ionic compound itself, is hard to break up its intermolecular
force it would be predicted that the boiling point would go up to dissolve the compound fully to
its boiling point.
