Formulate a hypothesis regarding the solubility of aspirin at different pH. 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?

✓ ?? 14. Two groups of students were asked to check the concentration of ammonia in a particular brand of cleaning product because there had been complaints about that brand. The students placed a 25.0mL sample of cleaning product in a volumetric flask and made it up to 250mL using distilled water. They then performed a titration by using 25.0mL of the diluted ammonia solution in a conical flask and 0.10 moll-¹ standardised hydrochloric acid in a burette. One group used bromocresol green (pH range 4.0-5.6) as the indicator and obtained the following results: Titration Volume of acid 1st 23.2 added (mL) 2nd 22.9 3rd 22.8 4th 22.9 a) Calculate the concentration of the diluted sample. b) Calculate the concentration of ammonia in 1L of the original sample.

To determine the Ksp of barium oxalate at 12°C, a 100.0 mL saturated solution was prepared by adding the solid in distilled water maintained at 12°C until it no longer dissolves. The solution was filtered and from this, a 10.0 mL aliquot of the filtrate was drawn. It was found out that 10.70 mL of 5.60 x 104 M HCI was used to reach the endpoint.
