Labreport25 | Chemistry homework help

1. What safety precautions must be taken with the material you are working with? 2. What common criteria for assessing water quality will you use? 3. Bring a water sample from the community. At the end of this project, you will compile your data with all other groups in your lab. Therefore, it will be important to note the date, time, and location of your sample collection. Water samples should be obtained from unfiltered sources. 4. Is there a criterion you can use to base your judgments on water hardness? 5. Which physical and chemical properties of your water samples will you test? 6. How can the water hardness be reduced? What is the material used in the water softener systems that reduces the hardness of water? 7. What is an ion exchange resin (sodium or mixture type)? 8. Is time a factor when using a filtration system? How long must the water be in contact with the filtration system?
