For each statement choose whether it is True or False. a. Decanting is a separation technique where you want to keep the liquid/aqueous phase of the product. False b. An evaporating dish could be used to recover or even dry a solid product. True C. Assuming no calculations errors, if the percent recovery was < 100% it could be due to loss of copper left in aqueous phase copper compounds. True d. Assuming no calculations errors, if the percent recovery was > 100% it could be because unreacted zinc is still left in the evaporating dish. True

1. List the precautions to be taken to keep a balance functioning correctly. 2 What is the most accurate reading when weighing a solid ? 3. Why cant large crystal be used for melting point determination ? 4. When using melting point to assess purity, how would you know that your sample is impure ?
A student determined fluoride in a toothpaste sample using ion chromatography. A toothpaste sample of mass 0.100 g was dissolved in type I water and then quantitatively filtered through a Whatman #1 filter paper into a clean 100 ml volumetric flask. The flask was then made up to volume with type I water and mixed thoroughly.A portion of the solution was filtered through a 0.45 um filter into a sample vial for analysis. Analysis of the sample gave a fluoride concentration of 1.60 mg/l Calculate the % w/w fluoride in the original toothpaste sample. (Give your answer to 3 decimal places please)

1. Develop a detailed separation scheme for the separation and determination of the percent composition of your sample which will be a mixture of NaCl, NH.CL, and sand. You are expected to use the properties of the components listed below and some of the techniques listed in the table in the pre-lab queries (and used in Separations I). Keep in mind that any chemistry student should be able to pick up your scheme, understand it, and use it to complete the separation and calculation of % composition. Place the scheme on a separate sheet of paper.
