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
9 -Molar mass of NaOH = 40 g/mol
10- Conc of NaOH in g/L = Molar mass of NaOH X M1 (stock NaOH) = g / L
