The pH scale (pH) is a numeric scale which is used to define how acidic or basic an aqueous solution is. It commonly ranges between 0 and 14, but can go beyond these values if sufficiently acidic/basic. pH is logarithmically and inversely related to the concentration of hydrogen ions in a solution. The pH to H + formula that represents this relation is

There exists both formic acid and acetic acid in a 1 liter solution of water. The overall solution pH is stated as 4.0 and it is also assumed that the 2 acids contribute equally to the pH. How do I then determine the molar concentration and quantity of each acid in the 1 liter solution. The density of formic acid 10% concentration is 1025 kg/m³ (see the densities table below). The volume we want to convert is 8 m³. Now, plugging these values in the formula above, we get: mass = density × volume = 1025 × 8 = 8200. So, 8 cubic meters of formic acid 10% concentration equals 8.2 × 10 3 kilograms Kg What is the molar concentration of hydronium ions in a 0.482 M solution of formic acid, given Ka = 1.8x10^-4.

Step-by-step answers are written by. The concentration of the unionized acid is equal to the original concentration minus the amount that ionized ( which is x). So the concentration of the HCOOH is written as [0.05 - x]. At this point, the argument is usually made that the ionized fraction of the formic acid is so small compared to the original concentration of the acid, that the x lost by the formic acid can be ignored
