How many ions will CaBr2 dissociate to in solution?
-cannot be determined
-3
-2
-0

3.

Explanation:

Hello there!

In this case, according to the definition of ionic bonds, whereby the cations give away their initial valence electrons to the anions, we infer that ionic species calcium bromide has three ions, one calcium ion and two bromide ions, and therefore the answer is 3.
