Solubility Curve Worksheet

Here is a solubility curve worksheet that you can use to practice interpreting solubility curves:

1. Study the following solubility curve for potassium nitrate (KNO3) and answer the questions below:

a) At what temperature does potassium nitrate have a solubility of 50g/100g water?
b) How much potassium nitrate will dissolve in 100g of water at 25°C?
c) At 80°C, what is the solubility of potassium nitrate?
d) Is potassium nitrate more soluble in water at 30°C or 70°C?
e) What is the general trend in solubility as temperature increases for potassium nitrate?

2. Study the solubility curve below for ammonium chloride (NH4Cl) and answer the questions:

a) At what temperature does ammonium chloride have a solubility of 60g/100g water?
b) How much ammonium chloride will dissolve in 200g of water at 40°C?
c) At 70°C, what is the solubility of ammonium chloride?
d) Is ammonium chloride more soluble in water at 15°C or 50°C?
e) What is the general trend in solubility as temperature increases for ammonium chloride?

Remember to use the given solubility curve to find the corresponding solubility values at different temperatures.
