We measured the pH of a 0.010 M formic acid (HCOOH ) solution and calculated the percent ionization to be 30%. Imagine the beaker of 0.010 M formic acid. If we could zoom in on the contents of the beaker, what would we observe in the beaker at the molecular level? Draw the beaker and show the dissolution of 10 molecules of formic acid (HA) where the percent ionization is 30%. Determine how many dissociated molecules to draw in your solution. You may use HA rather than the full Lewis structure to represent formic acid. Omit water molecules from your drawing.
