WebIf it breaks any rules I apologize. I received a pka file for use with packet tracer, and completed the steps issued in the instructions. But my completion is stuck at 98%. A … WebApr 26, 2014 · First, you can determine the equilibrium constants for each acid from the pH values of their aqueous solutions (before mixing). The corresponding pKa values are 3.74 and 4.78 for formic and acetic acid, respectively. After mixing, the concentration of total formic acid and total acetic acid drop by a factor of 2 (mutual dilution). WebMar 14, 2024 · Ka = 10 (-pKa) When pKa is a whole number, such as -7, this operation is easy to perform, but when it contains a fraction, such as 7.5, you may have to look up the value in a table.
