3/27 Class Practice; solubility curves

When you plot data and the data point ends up on the curve, the solution is saturated.

Below the curve, data points are unsaturated, and supersaturated data points are above the curve.

​

Types of solutions

We can find the amount of solutes that can be dissolved at any given temperature.

You may also need to know what temperature a given amount of solute will dissolve

​

Reading Solubility Curves

Example: How much potassium chloride would dissolve in 250 grams of water at 40 degrees Celsius?

​

Being able to use math to figure out how much you could dissolve.

Example: How much potassium chloride would dissolve in 250 grams of water at 40 degrees Celsius?

​

39 C dissolves in 100 g of water

Being able to use math to figure out how much you could dissolve.

Example: How much potassium chloride would dissolve in 250 grams of water at 40 degrees Celsius?

​

39 = x

100 250

Being able to use math to figure out how much you could dissolve.

Example: How much potassium chloride would dissolve in 250 grams of water at 40 degrees Celsius?

​

39 x 250 = 97.5
