Solubility Curves

By: Melissa Pulley and Tyler Landry

Solubility: amount of substance that dissolves in a given amount of solvent

Solubility curve: the graph/chart showing how much of a substance can be dissolved at a given temperature

In ionic compounds (salts), solubility usually increase when temperature increase, and as solubility decrease temperature does as well.

However, gases get less soluble as the temperature increase.


1) What is the solubility of NaNO3 at 50°C?

2) At what temperature is the solubility of NH4Cl ~50g/100g H2O?

3) A. You have a beaker filled with 100 mL (100g) of water, into which you have stirred 40g of KCl at 60°C. Is this solution saturated?
