Unit: Principles of Chemistry
Topic: Solubility
You are given 10 ml of water at
room temperature (check room
temperature using a thermometer).
Starter
Think, Pair, Share
Conclusion: The solubility of salt
In 100 g of water is 36 g
Predict how many grams of salt can
be dissolved in 10 ml of water.
Perform an experiment to test your
prediction/s.

Different compounds will
have differing solubilities in

Solubility Curves
●
A graph of solubility against temperature
is known as a solubility curve.
Solubility curves are used to find the
solubility of a substance at a specific
temperature.
○
○
A line is drawn from the X-axis (temperature)
up to the curve.
A line is then drawn from the curve to the Yaxis (solubility).

The solubility of solid potassium
chlorate (KClO3) in water increases as
the temperature increases.
