Two buffers are prepared by adding an equal number of moles of formic acid (HCOOH ) and sodium formate (HCOONa ) to enough water to make 1.00 L of solution . Buffer A is prepared using 1.00 mol each of formic acid and sodium formate. Buffer B is prepared by using 0.010 mol of each. (Ka(HCOOH)=1.8*10^ -4 .
