4. A solution is prepared that contains 0.0445 mol of sulfuric acid in a total solution volume of 12.1 L. Sulfuric acid typically undergoes complete ionization according to the equation: H2804 > 2H' + 8042' Calculate [H']. Sulfuric acid is a strong acid. 5. Phosphoric acid is a weak acid that undergoes the following ionization reaction: HaPCMaq) '-' H+(aq) + HzF'Odaq) If there are 1.32 x 10-2 mole of phosphoric acid present in 875 mL of solution. calculate the concentration of hydrogen ions, H2 in solution. K. for phosphoric acid is 7.0 x 10\". Begin by calculating [H3P04]. Then use Ka to determine [H*]
