Problem- You are working in the laboratory and you need to make a formic acid solution of a certain concentration. The lab is out of formic acid (HCOOH), but you find a formic acid solution in the laboratory refrigerator with no concentration label, but you measure the pH and find that it has a pH of 2.8. You know that the pKa for oxalic acid is 3.75. Knowing this information calculate the concentration of the oxalic acid in solution in (mol/L) and in (mg/L) assuming that equilibrium conditions exist between the formic acid and water in solution.
HCOOH <-------> HCOO^- + H^+
I am in need please provide me complete solution for the above problem so I can get right solution
