Dangerous Paint Stripper Jessica has a summer job working for the city parks program. She has been using a cleaner called “Graffiti Gone” to remove graffiti from the bathrooms. She has to take a lot of breaks, because the chemical makes her throat burn. It also makes her feel dizzy sometimes, especially when the bathrooms don’t have very many windows. On the label, she sees that the cleaner has methylene chloride in it. She feels like she’s managing to get the work done, but she is worried about feeling dizzy. She wants to find out more about this chemical, what harm it can cause, and whether there are safer ways to do this work. Questions for following story. 1. What went right in this situation? 2. What went wrong in this situation? 3. What steps should be taken in this workplace to make sure employees are better protected and prepared the next time?

1) Listen -5 The Ksp value for calcium sulfate [CaSO4] is 2.40 X 10 and a professor made 1825 mL of a CaSO4(ag) solution but then one of his graduate student accidentally poured in a 0.125 M solution of calcium phosphate [Cag(PO4)2] solution. You may ignore the additional volume coming from the Ca3(PO4)2 solution to make the calculation simpler. Calculate the new sulfate (SO42) ion concentration at equilibrium with this common ion effect. 6.40 x 10-5 5.25 x 10-5 6.21 x 10-5 5.44 x 10-5 201591..docx LAB EXP. #3 -..docx Show All
