1mL of the stock solution acetaminophen (1mg/mL) is used for the estimation of PC using n-octanol. After extraction, 0.1mL of the extracted solution was added to 0.9mL of water and 100uL of this solution was loaded in 96 well plate to the absorbance at 260nm. If the observed absorbance of the extraction phase is 0.2 using the following standard curve equation, Calculate the concentration of acetaminophen in aqueous Phase. Note: If you need the standard curve equation, please make It up because I want to understand the concept.

Hi! For the first part, you need to put appropriate reagent (found below the diagram) to the space provided that will yield the given results. For the second part, you need to determine the reagent/s needed to confirm the identity of the cation from question 1. There can be more than one answer.    Thank you!

Processing of results Calculate (and show your calculations) for each acetic acid solution 1. the molar conductivity, Am (S m² mol¹), 2 the degree of ionisation, a 3. the ionisation constant, Ka 4. [H3O] = αcм and the pH = -log [H3O+]. Finally, calculate an average value for the ionisation konstant, Ka, of acetic acid with its standard deviation. Compare your result with a literature value and make a statement whether it is significantly different or not.
