The reaction being demonstrated is a neutralization reaction, where an acid and base are combined in order to form a salt and and water. Here, the acid is HI and the base is Ca(OH)₂. The net ionic equation for neutralization reactions is:
H⁺(aq) + OH⁻(aq) → H₂O(l)

Thus, the answer is C.

Answer:

The correct answer is option c

Explanation:

Hello!

Let's solve this!

The reaction is a neutralization reaction:

2HI (aq) + Ca (OH) 2 (aq) ---> CaI2 + H2O

Where CaI salt is formed with iodine and calcium and on the other hand water is formed.

In the formation of water we have to:

H + (aq) + OH-2 (aq) ----> H2O (l)

So we conclude that the correct answer is option c
