1. An aqueous solution is prepared such that pH = 8.2. Determinethe [H+] [OHâ€“], and pOH of this solution. Show work.
2. Below are the relative fraction of species versus pH curvesfor different acids. Based on these curves, rank the acids(carbonic acid (H2CO3), bicarbonate (HCO3 â€“), phenol (C6H5OH),hydrofluoric acid (HF)) in order of increasing acid strength.Briefly describe reasoning.
3. According to the list of bases in order of increasing basestrength up the page, which side of the acid-base reaction shownbelow is favored at equilibrium? Briefly explain. HPO4 2â€“ (aq) +HSâ€“ (aq) H2PO4 â€“ (aq) + S2â€“ (aq) Base: Strongest OHâ€“ S2â€“ PO4 3â€“HPO4 2â€“ HSâ€“ H2PO4 â€“ H2O Weakest
4. Below are the chemical structures of three species labeled A,B, and C. One is an acid, one is a base, and one is neither an acidnor a base when dissolved in water. Assign which one is which andbriefly explain assignments.
