The dibasic compund B(pkb1=4.00),pkb2=8.00 was titrated with 1.00 M HCl. the intial solution of B was 0.100M and had a volume of 100.0mL.A) At what volumes are the two equivalence points?B) find the pH at the folowing volumes of acid added(Va) and sketch a graph of pH versus Va: 0.0,5.0,10.0,15.0,20.0 and 22.0ml
A 0.0100 L sample of H2SO4 (Sulfuric Acid) was titrated with 0.150 M NaOH. It took 23.3 mL of NaOH from the buret -- that's 0.0233 L -- to reach the titration endpoint.
