0.02000 M NaOH to reach the equivalence point. What is the concentration of unknown HNO3 solution? 2) A 15.0 mL sample of 1.78 x 10-3 M Ca(OH)2 is being titrated against 2 M HCI. Determine the volume of HCl needed to reach the equivalence 3) A 30.00 mL sample of unknown concentration of H3PO4 solution is titr 0.100 M Ba(OH)2 solution. The equivalence point is reached when 26.. Ba(OH)2 solution is added. What is the concentration of the unknown H solution? 4) A 35.0 mL sample of 1.78 x 10² M H2C,O4 is being titrated against 2.1 HBr. Determine the volume of HBr needed to reach the equivalence po 5) Acetylsalicylic acid (HC,H;O4) is a monoprotic acid commonly known "aspirin". A typical aspirin tablet, however, contains only a small amou acid. In an experiment to determine its composition, an aspirin tablet w and dissolved in water. It took 12.25 mL of 0.1466 M NaOH to neutral solution. Calculate the number of grains of aspirin in the tablet (one gra 0.0648 g). (assume acid:base ratio is 1:1).
