Arthur Wen, a CHEM 18.1 student, was tasked to make a 250mL solution of NaCH3COO with pH = 9.022 for their laboratory class. However, he forgot to take note of the initial concentration needed and was too shy to ask Mr. Lee, his teacher. He knows that the conjugate acid of one of the salt's ions has a Ka = 1.8 x 10-5. 1. Compute for the initial concentration (M) of NaCH3COO: M 2. Compute the mass (g) of solid NaCH3COO to prepare the said solution:

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-.
