How was the precipitate obtained after filtration? By scraping from the filter paper and transferring to a watch glass. By redissolving in hydrochloric acid. By drying the precipitate on the filter paper using a desiccator. By charring the filter paper and igniting the product in a crucible.
In a similar experiment, the mass of 3 PB tablets was measured to be 3.1823 g. The tablets were crushed, and 2.9801 g of the powder was transferred to a beaker and reacted with HCl. After filtration, the filtrate was transferred to a 50-mL volumetric flask and diluted with water. 10.00 mL of this stock solution was combined with 0.2 M Na3PO4.

Use the attached pictures to help fill in the rest of the data. Please note that I used 0.79g of KMnO4 to prepare 250ml of 0.02M solution to titrate the ferrous ammonium sulfate. The approximate 1g of ferrous ammonium sulfate contained 25ml of distilled water and 10ml of 1M H2SO4 : H3PO4 to help dissolve the mixture for part one. For part two, the same steps were used however, we are to determin the amount of Fe in the sample. Please show and explain your work for each trail. Thank you!
