- 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-.Please Answer my question from the picture im send... And note With same dengan.. God bless you ..

- Explain how (the dreaded chemistry) the addition of alum decreases alkalinity and tends to lower the pH of the treated water. (you may want to have a separate slide or graphic to help you explain this).The molar concentration of H3O+ was measured at 25 ° C. The pH and pOH should be calculated for the following [H3O+] (ideal solution) when a. [H3O+] = 15 μM b. [H3O+] = 1,5 mmol/dm3There are two different types of reactions that NaI might undergo with concentratedsulfuric acid in Part E. Describe and write balanced equations for both possibilities. From Part E: Reactions with NaI and NaCl17. CAUTION: 18 M H2SO4 is extremely caustic. Handle it with care.18. This part will utilize the “Testing for an Acidic or Basic Gas” technique described in Appendix B.1419. Collect about 2 dropper’s worth of 18 M H2SO4 in a small tube and take it to your workstation for this part;don’t perform the following reactions in the main hood where this acid is kept.20. Place a small quantity (about the same amount of solid used for part D above) of NaI in a clean dryevaporating dish. Place the same amount of NaCl in a separate dish.23.
