78. A 0.446-g sample of an unknown monoprotic acid is titrated with 0.105 M KOH. The resulting titration curve is shown here. Determine the molar mass and pK, of the acid. pH OOO 0 20 40 60 80 100 Volume of base added (mL)
A sample of 0.1387 g of an unknown monoprotic acid was dissolved in 25.0 mL of water and titrated with 0.1150 MNaOH. The acid required 15.5 mL of base to reach the equivalence point.
Part B After 7.25 mL of base had been added in the titration, the pH was found to be 2.45. What is the Ka for the unknown acid? (Do not ignore the change, x, in the equation for Ka.)
Item 8 A 70.0 mL sample of a monoprotic acid is titrated with 0.140 MNaOH.
Part A.) If 22.0 mL of base is required to reach the equivalence point, what is the concentration of the acid?
