A) Acidic and after the equivalence point
B) Basic and after the equivalence point
C) Neutral and at the equivalence point
D) Basic and before the equivalence point
E) Acidic and before the equivalence point

  1. millimols HCl = M x L = 0.150 x 35 = 5.25
    millimols KOH = M x L = 0.250 x 35 = 8.75
    ........HCl + KOH ==> KCl + H2O
    It should be obvious that all of the KOH has not been neutralized by the HCl so the solution will be basic. It will take another 8.75-5.25 = ? mols HCl to finish the neutralization
