A20.0-ml sample of 0.30 m hclo was titrated with 0.30 m naoh. the following data were collected during the titration. determine ka for hclo. data provided: ml naoh added ph 5.00 6.98 10.00 7.46 15.00 7.93 20.00 10.31 (hint: find the volume of naoh at equivalence point)

Explanation:

We know at equivalent point,

So, equivalent point is obtained at 20 ml.

Therefore, half equivalent point is obtained at 10 ml.

Also , at 10 ml NaOH , pH= 7.46 .

We know,

Also,

Taking anti log both sides .

We get

Hence, it is the required question.

the answer is   c.) 1575 j.
