It requires 23.2 mL of 0.250 M KOH to titrate 49.0 mL of an HCl solution of unknown concentration. Calculate the initial HCl concentration.

  • chemistry -

    HCl + KOH ==> KCl + H2O
    Note the ratio is 1 mol KOH = 1 mol HCl.

    mols KOH = M x L = ?
    mols HCl = mols KOH
    MHCl = mols HCl/L HCl
    Done.
