Doc Inmaking does a titration using sodium hydroxide (NaOH) and sulfuric acid (H2SO4). He pipets 20.00 mL of H2SO4 solution into the Erlenmeyer flask and adds two drops of phenolphthalein. He does the titration using 0.5000 M NaOH. The initial buret reading is 0.70 mL and the final buret reading is 35.23 mL. Write the balanced chemical equation for sodium hydroxide reacting with sulfuric acid to produce sodium sulfate and water. Determine the mole ratio between the acid and the base. (Hint: it is not one-to-one.) Then calculate the molarity of the sulfuric acid (H2SO4) solution. Enter the H2SO4 concentration with 4 significant digits and units of mol/L.
