Question

3. Consider the analysis of the ammonia content in this experiment. If the buret used in the titration was rinsed with distilled water, but not dried or conditioned before use, would the calculated number of moles of ammonia per gram of complex be too high, too low, or unaffected? Briefly Explain. If the titration flask was rinsed with distilled water but not dried before use, would the calculated number of moles of ammonia per gram of complex be too high, too low, or unaffected? Briefly Explain.

Answer 1

While performing the titration, you need to rinse the burit with distilled water and dried completely to get accurate and reliable results. But if the buil Jured in the titration was rinsed with distilled wated but not dried or conditioned Befou we, would definitely change the calculated number Of midles of ammonia per gram because the remaining traces of water present on side of the buret would affect the reading since the titraut would become more celule and will definit bly change wits concentration. ' I white ich you rinse the buret will the same colution as ured in the buret te ammonia it would not change the concentration of the solution. for the titration Alark that was delibed washed with distilled water but was het dind before use. would not have any affect on the calculated number of moles of ammonia perlu gram of complex because the moles of chemical (ammonia) pruent inside the flack remains unaffected by presence of any amount of distilled water.
