- Please don't provide handwrittrn solution...correct this scheme and highlight what needs to be correctedA 5.000-g soil sample was analyzed for potassium content by extracting the potassium using 10.00 mL aqueous ammonium acetate solution. Following the extraction, the soil was filtered and rinsed. The filtrate with rinsings was diluted to exactly 50.00 mL. Then, 1.00 mL of this solution was diluted to 25.00 mL, and this dilution was tested with an instrument. The concentration in this 25.00 mL was found to be3.18 ppm. What is the concentration of the potassium in the soil in ppm?
- 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!The separation and purification processes given below and the method used against them are given. Which or which of these pairings are correct? I. Brewing of tea - ExtractionII. Purification of water impurities - ChromatographyIII. Separation of olive pomace from olive oil while producing olive oil-DecantationIV.Petroleum fractions obtaining - Ordinary distillationV. Obtaining essential oils and using them in perfume making - Water-steam distillationIf a mixture is distilled rapidly, the separation of its compound is poorer than if the mixture is distilled slowly. Please explain why is that so using your own understanding. I don't need a copy-pasted answer from google.
