You've just started your summer intern as a research assistant in the biology department. Your first assignment is to prepare a pH 7.50 phosphate buffer solution to be used in the isolation of DNA from a cell culture. You've discovered the following items available to you in the lab: 0.514M HPO 4 (K a-4.2x10 13) 48.6 g KOH (molar mass - 56.1g) a. Calculate the pH of your buffer. b. Do you think that this would be a suitable buffer? Explain. SHOW YOUR WORK. Upload your file here.

The first step in purifying the urine collected on the ISS is to treat every liter of urine with 20 mL of 1.0 M H2SO4. To simplify the calculations, lets assume that urine is water. a) What is the pH of a solution of 20. mL of 1.0 M H2SO4 added to 1.00 L water? To determine this, you can safely assume that 100% of the H2SO4 reacts to form H3O+ and HSO4- ions. Use pKa2 (1.92) to determine if any more protons are added to the solution from HSO4-.
