Hello please help with number 4.
"HdJuaap je uijidse 1o Auonios aun Buipueaau sisa
The experiment
A) Three teaspoons of water (approx. 15 ml) were added to one tablet said to contain 300 mg of aspirin. Fizzing
was observed. Most of the tablet dissolved, but there were some solid particles. By heating the mug in a
microwave for 10 second increments until the water came to the boil (approx. 3x), all of the solid particles
dissolved. The solution was left to cool to room temperature and then placed in a fridge and NOTHING
HAPPENED. Try this yourself if you can spare two aspirin tablets, your results might look different.
Questions to ask:
1. What might the fizzing bubbles be?
2. Can you give a chemical explanation?
3. Can you write a chemical reaction equation with aspirin reacting with something to give a gas and aspirin
in another form?
What might be the formulation (what the manufacturer mixes with aspirin in making the tablet) "trick"
for aspirin to improve solubilitV?
How does this compare with the published solubility of aspirin in water- this is a physical property of
an organic compound.
