A student determines that she used 0.0665 mol of sodium hydroxide (NaOH) to completely titrate 25.00 mL of sulfuric acid solution (H2SO4). What is the molarity of the sulfuric acid?
0.00131 M
0.00262 M
1.31 M
2.62 M
For a titration procedure, one must know the reaction going on in the steps involved. For this case, it is the reaction between NaOH and sulfuric acid.
2NaOH + H2SO4 = Na2SO4 + 2H2O
With the reaction and the values given we calculate as follows:
