3 Part A.2. Some spattering of the sample onto the watchglass does occur near dryness. In a hurry to complete the analysis, the chemist chooses not to return the spattered solids to the original sample and skips the first part of Part A.3. Will the reported TDS for the water sample be too high or too low? Explain. 4. Part A.3 and Part B.2. The sample in the evaporating dish is not heated to total dryness. How will this error in tech- nique affect the reported value for TDS-too high, too low, or unaffected? Explain. TSS-too high, too low, or unaf- fected? Explain 5. Part A.3. As the sample cools, moisture from the atmosphere condenses on the outside of the evaporating dish (beaker) before the mass is measured. Will the presence of the condensed moisture increase or decrease the reported TDS in the water sample? Explain. 6. Parts B.1 and B.2. The sample in the evaporating dish (beaker) is not heated to total dryness. As a result of this tech- nique error, will the reported value for total solids (TS) be too high, too low, or unaffected? Explain. 7.Parts A and B. Suppose the water sample has a relatively high percent of volatile solid material. How would this have affected the reported mass of: a. dissolved solids-too high, too low, or unaffected? Explain. b. total solids-too high, too low, or unaffected? Explain. c. suspended solids-too high, too low, or unaffected? Explain. 8. Part D.2. When several drops of 0.010 M AgNO3 are added to a test sample, a white precipitate forms. What can you conclude from this observation? Explain. 3 Part A.2. Some spattering of the sample onto the watchglass does occur near dryness.
