The flask shown here contains 10.0 mL of HCl and a few drops of phenolphthalein indicator. The buret contains 0.270 M NaOH.

What volume of NaOH is needed to reach the end point of the titration?

What was the initial concentration of HCl?

    You don't have enough information posted to work the problem; I assume the picture to which you refer gives the volume of NaOH.
    mols NaOH = M x L = ?
    mols HCl = mols NaOH
    M HCl = mols HCl/L HCl.

    Vol NaoH titration Ml Naoh (1L/1000 mL) (.270 M (NAOH)= mol NaOH

  • Chemisty -

    Then mol of NaOH mol HCL/.010L
