Consider that 25.0 ml of 0.10 m ha (an arbitrary weak acid. k = 2.5 x 105 is titrated with 0.10 m naoh solution. answer the following questions. [18 pts] a) what will be the initial ph of the 0.10 m ha solution? [4 pts] b) what will be the ph of the ha solution after the addition of 10.0 ml of 0.10 m naoh to the solution? [5 pts)
calculate the ph at the halfway point to the equivalence point. [4 pts d) calculate the ph at the equivalence point.
