- 1. The substance to be analyzed – is white, highly soluble in water salt. Reaction with NaOH gives white precipitate, soluble in reagent surplus. When interacting with dithizone – changing of color of organic layer to red is observed. Addition of iron (III) chloride leads to changing of solution`s color to reddish- brown. What kind of substance is this? Explain you answer, provide chemical equationsThere are two different types of reactions that NaI might undergo with concentratedsulfuric acid in Part E. Describe and write balanced equations for both possibilities. From Part E: Reactions with NaI and NaCl17. CAUTION: 18 M H2SO4 is extremely caustic. Handle it with care.18. This part will utilize the “Testing for an Acidic or Basic Gas” technique described in Appendix B.1419. Collect about 2 dropper’s worth of 18 M H2SO4 in a small tube and take it to your workstation for this part;don’t perform the following reactions in the main hood where this acid is kept.20. Place a small quantity (about the same amount of solid used for part D above) of NaI in a clean dryevaporating dish. Place the same amount of NaCl in a separate dish.23. Lift one of the watch glasses just enough to add one dropper’s worth* of 3 M H2SO4 to the salt inside andthen quickly replace it.25.

- 1. Why is the KMnO4 solution filtered? KMnO4 doesn't need to be filtered prior to use. Most commercial samples of KMnO4 contain some manganese dioxide that must be removed prior to use to avoid further decomposition. KMnO4 is very stable, but the unstable ions in the commercial packaging materials must be removed prior to use. Most commercial samples contain inorganic matter that will react slowly with the KMnO4 and cause its decomposition. 2. Why is the KMnO4 not stored in a rubber-stoppered bottle? Rubber doesn't make a good seal with the plastic bottles in which permanganate is usually stored. Rubber is made of inorganic matter and will reduce the permanganate solution. Rubber is made of organic matter and will reduce the permanganate solution. Rubber can oxidize the permanganate solution.A 1.000-g sample containing bromide was dissolved in sufficient water to give 100.0 mL.
