Mini Titration

According to Bronston and Lowry, an acid is what donates a proton (or H+) in a reaction and a base is the acceptor. All acid-base reactions are neutralization reactions, and produce salt and water. Tirtration is an analytical technique used to calculate the concentration of a solute in a solution. Since we are a bit rusty in our chemistry game, this titration  lab helped us (or me, at least) get back in the swing of molarity. Our goal was to determine the molarity of a dilute solution of sulfuric acid. To do this, we measured 20 mL of the H2SO4 in a flask. Then measured approximately 50 mL of NaOH into a buret. After placing the flask with the sulfuric acid solution onto a magnetic stir plate, 2 drops of phenolphtaleine was added as an indicator. Drops of the sodium hydroxide was added until the solution was a very light pink (not dark pink). This indicated the molatiry of the solution was the same as the 1M NaOH. This took several tries, however (with the execption of Sophia's group, of course). After a couple tries we concluded that it took exactly 18.4 mL of NaOH to neutralize the acid.Therefore, .0184mol of NaOH we used. Then we then multiplied that by the mole ratio of H2SO4 to NaOH, which told us we used .0092 moles of H2SO4. We then divided this by .020L of the H2SO4, giving us the molarity of 0.46M.
