You are performing an experiment in lab that involves the titration of 25.0 mL of H2SO4 solution. You titrate the acidic solution with 0.8067 M NaOH and the equivalence point is reached by the addition of 17.31 mL of NaOH solution. Using the balanced equation below, calculate the molartity of H2SO4 in the flask. Do NOT include units. 2NaOH(aq) + H2SO4(aq) --> 2H2O(l) + Na2SO4(aq)

In the scary chemical storage room, you spot a bottle of potassium hydroxide solution, KOH, without a label noting its concentration! How terrible! (the nerve of some people...) Since you love chemistry, you decide to figure out its concentration by doing a titration. You add 5.00mL of 0.100M phosphoric acid to a flask and add KOH solution until it's all neutralized! If 5.00mL of potassium hydroxide solution were used in the titration, what is its concentration? 3.00 M 0.900 M 5.00 M 0.100 M 0.300 M
