Which of the following gives the net ionic reaction for the reaction used in this experiment?
h+(aq) + oh-(aq) → h2o(l)
no net reaction
ba2+(aq) + so42-(aq) → baso4(s)
ba2+(aq) + 2 oh-(aq) + 2 h+(aq) + so42-(aq) → baso4(s) + 2 h2o(l)

Option (d) is the correct answer.

Explanation:

The given reaction will be as follows.

In the ionic form, the equation will be as follows.

            ........ (1)

            ............ (2)

Hence, for the net ionic equation we need to add both equation (1) and (2). Therefore, the net ionic equation will be as follows.

Now, balancing the atoms on both the sides we get the net ionic equation as follows.
