What volume of 0.175 M solution of KOH is needed to titrate 30.0 mL of 0.200 M H2SO4? If 79.5 mL of an aqueous solution of perchloric acid is needed to neutralize 50.0 mL of a 0.0750 M aqueous solution of barium hydroxide in a titration, what is the pH of the original perchloric acid solution solution?
1. Calculate the volume (in mL) of the amount of 0.200 M NaOH required to neutralize a monoprotic weak acid solution made by 2.00 g of potassium hydrogen phthalate (KHP) dissolved in water. Hint: the complete neutralization occurs at the equivalence point, where the number of moles of the analyte (in this case, the weak acid) equal to the titrant (in this case, the strong base). 2. Identify the equivalence point, the half-equivalence point on the titration curve below and...
