Pre-Lab Assignment Hydrogen Phosphate Buffer System This pre-lab assignment is mandatory. You will receive a zero for the experiment if the pre-lab assignment is not completed before the beginning of the lab session. 1. Calculate the masses of the conjugate acid and base needed to prepare each of the six buffer solutions listed in the table on the left. (p of H,PO,= 6.70) Assume the availability of the phosphate salts listed in the table on the right. Fill out the...

In a lab experiment: iodination of propanone. Iodine and propanone are mixed. The raection is stopped at intervals by adding a portion of sodium hydrogen carbonate solution. This is then titrated against sodium thiosulphate. A graph was plotted of sodium thiosulphate volume VS time although sodium thiosulphate does not take part in the reaction. Why is this acceptable? Would it be more accurate to work out the iodine concentration and plot this instead? Also, how does one ascertain the dependence...

Quantification of Total Protein Using Bradford Protein Assay Pre-Lab Your pre-lab assignment is to plan how you will prepare your BSA standard solutions for the calibration curve. A 2 mg/mL BSA stock solution will be available. You can simply dilute with deionized water. You will need to make 25 microliters of each of the following concentrations. For the first concentration, you will need to make 160 microliters so that the BSA volume is large enough that it can be measured...
