A 25 mL solution of H2SO4 is neutralized by 18 mL of 1.0 M NaOH using phenolphthalein as an indicator. What is the concentration of the H2SO4 solution? Equation: H2SO4 + 2NaOH ( Na2SO4 + 2H2O. 1) How many mol of NaOH are needed for neutralization? 2) How many moles of H2SO4 were neutralized? 3) Calculate the concentration of the acid:

8) Perform the following molarity/normality problems: What is the normality of a 5.0 M phosphoric acid (H3PO4) solution? Find the normality of 5.6 g HBr in 450.0 mL of solution. If 45.0 mL of 0.30 N H2SO4 are neutralized by 75.0 mL of NaOH, find the normality of the NaOH. A 43.7 mL sample of Ba(OH) 2 is neutralized by 33.5 mL of 0.86 M HCl.

Where Normality = Molarity (moles/L) * the number of hydrogen exchanged in a reaction (eq/moles) ... If the color of the solution turned blue, titrate your sample with 0.02 N H2SO4 or HCl (you may need to dilute the acid provided in the lab) until the color changes to yellow (pH 4.5). Record the total volume of acid used for the titration.

1.5M HCl x 1 H+ = 1.5N HCl (an acid with 1 H+ will have the same normality as molarity) 1.5M H2SO4 x 2 H+ = 3.0N H2SO4 . 1.5M H3PO4 x 3 H+ = 4.5N H3PO4 . The normality shows that even though the molarity of each acid was the same, the H3PO4 can neutralize more base because of its added H+.
