Formic acid is a weak acid along with a pKa of 3.75. The name comes by the Latin term "formica" ("ant") since this is very plentiful into the secretions of several species of ants, and is exact of the irritants delivered by several stinging ants, wasps and bees.
When use formic acid to make 2.00 liters of 50.0 mM buffer at the pH that selected, determine the equilibrium concentrations expect for formic acid and its conjugate base.
Ans:
[Hform] = 0.017999 M → 0.0180 M formic acid
[form-] = 0.032001 M → 0.0320 M formate
