Ex .3 Data Sheet                               Using dilution Factor in an Acid Base Titration.

HCl   (aq) + NaOH (aq)                NaCl (aq)   + H2O (aq)

HCl Solution        

M1    (HCl )    X   V1     ( HCl )        = M2   ( HCl )          X   V2 ( HCl )          

1.00 mol/L     X     4.00 ml      =       M2   ( HCl )       X     100.0 ml                   

Molarity of diluted   HCl Solution M2 =                                mol / L   

NaOH Solution

1 - Volume of   NaOH needed for dilution V1 =     10.00   ml

2 -Total volume of diluted NaOH V2   =   100.0   ml

3 - Dilution Factor   = V2 / V1   =100ml / 10 ml    =

4- Volume of HCl used in Titration V HCl = 10.0 ml

5- Moles of HCl   =   M2 (0.04 mol/L ) x VHCl   0.01    (L)   =                                  moles   

6-Moles HCl   = Moles of NaOH   

7- Molarity of   diluted NaOH   Solution M2 =   moles NaOH    / V ave (L) =                   mol/ L                            

8- M of (Stock )   NaOH   Solution M1 = M2   x Dilution Factor   =                       mol / L
