The Effect of Substances on Boiling Point Lab Experiment
Directions :
Interpret the following data from a lab experiment. Use this information to help you create a graph and
complete the analysis questions that follow.
Lab Data:
Table 1. Table displaying
mass of sugar dissolved
in water and boiling
point temperature for
the water.
Mass of Sugar
(g)
Boiling Point
Temperature (°C)
50.0
100.5
100.0
101.0
150.0
101.8
200.0
102.2
250.0
102.6
300.0
103.1
Make a graph of the data above using the blank template below. Be sure to include a title, both axis labels
with units, accurate increments, and draw a line through your data points.
Post-Experiment Analysis
1) Using the graph you created, what is the relationship between increasing the
mass of the sugar and the boiling point of the water?
2) Calculate the slope of the line you made using the following equation:
y2-y1 / x2-x1.
3) Extend your line back to the y-axis and determine the value of the y-intercept
with correct units (*Note: this value should NOT be zero).
4) Write the equation of the line (y = mx + b) using your value for slope and yintercept.
5) Using the equation of your line, determine the temperature that the water
will boil if 500.0 grams of sugar are added.
6) Using the equation of your line, what would be the mass of sugar added if
the boiling point was found to be 101.4°C?
7) When boiling pasta, salt is often added to the water to add to the flavor.
Explain in detail how this will impact the time it takes for the water to boil.
8) Adding substances to water will decrease the point at which water will
freeze. Provide an example of how this property is useful in a real world
situation.
