The Handbook of Chemistry and Physics (http://openstaxcollege.org/l/16Handbook) gives solubilities of the following compounds in grams per 100 mL of water. Because these compounds are only slightly soluble, assume that the volume does not change on dissolution and calculate the solubility product for each. (a) BaSeO4, 0.0118 g/100 mL. (b) Ba(BrO3)2H2O, 0.30 g/100 mL. (c) NH4MgAsO46H2O, 0.033 g/100 mL. (d) La2(MoO4)3, 0.00179 g/100 mL

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 partides 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? 4. What might be the formulation (what the manufacturer mixes with aspirin in making the tablet) "trick" for aspirin to improve solubility? 5. How does this…
Be sure to answer all parts. From the solubility data given, calculate the solubility products for the following compounds. (a) SrF2, 7.3 × 10-² g / L: x 10 Enter your answer in scientific notation. (b) Ag3PO4, 6.7 × 10-3 g / L: x 10 Enter your answer in scientific notation.
Twenty sodium salicylate tablets labeled 325 mg were dispersed in sufficient water to make 200.0 ml. A 15.0-ml aliquot of the filtrate was titrated to a bromophenol blue end point in the usual way by 29.11 ml of 0.1000 N hydrochloric acid. Calculate the amount of sodium salicylate in each tablet and, from that, the percentage of the labeled amount. Hint: Use the above formula.
