Which statement accurately contrasts flame atomization and graphite furnace atomization in Atomic Absorption Spectroscopy (AAS)? Flame atomization requires smaller sample volumes compared to graphite furnace atomization, which is more suitable for bulk analysis. Graphite furnace atomization achieves higher temperatures than flame atomization, often resulting in better sensitivity and lower detection limits. Flame atomization is typically used for solids and high-viscosity liquids, whereas graphite furnace atomization is preferred for volatile liquid samples. Graphite furnace atomization is a less precise method than flame atomization due to the inhomogeneity of the sample matrix within the furnace.

Sodium thiosulfate pentahydrate can be produced by boiling elemental sulfur in an aqueous solution of sodium sulfite. S$(s) + NazSO3(aq) + H2O(!) → Na,S2Oz-5H2O(s) (unbalanced) What is the theoretical yield of sodium thiosulfate pentahydrate when 3.10 g of sulfur is boiled with 13.9g of sodium sulfite?

Quantitative Analysis by External Standard Method Calcium in a juice sample is determined by atomic absorption spectrophotometry. A stock solution of calcium is prepared by dissolving 1.834 g of CaCl, 2H20 in water and diluting to 1000.0 mL. A substock calcium solution was prepared by transferring 10.00 mL of the stock to a 100.00 mL volumetric flask and diluting to the mark. Three standard solutions of calcium were prepared by transferring 2.500 mL. 5.00 mL and 10.00 mL of substock to 50.00 mL volumetric flasks and diluting to the mark. The sample is prepared by transferring 1.000 mL of fruit juice from the original bottle to a 25.00 mL flask and diluting to the mark. Strontium chloride is added to all solutions before dilution to avoid phosphate interference. Instrumental response of the standards is measured against the blank, and the following readings are recorded: 9.10, 18.6 and 37.0. The sampie reading is 28.1. Using the multipoint method, find the concentration of calcium in…
