Consider the electrochemical cell: Pt|Cr2+(0.2752 M), Cr3+(1.705 M)||Co2+(0.2008 M)|Co a. What is the cell potential (hint: you can solve the problem by half-reactions or by the over-all reaction, both will give you the same answer so you can double check yourself)? b. Is the cell galvanic or electrolytic (must show math i ...continues
Diprotic Acids and Solution Equlibria
2. A 1.200 M solution of HCl is added to a solution containing 0.150 moles of sodium phosphate (Na3PO4). The resulting solution is then diluted to exactly 0.500 L, at which time the pH was found to be pH 8.00. What is the concentration of H2PO4- and HPO4-2 in the solution and how many mL of HCl were added? (For phosphoric acid ...continues
