Question

Does the Ba(OH)2 solution contain ions?

Answer 1

Yes. It does contain Ions. 

Answer 2

Answer:

Yes Ba(OH)2 solution contain ions.

Explanation:

Actually Ba(OH)2 is a strong base which is completely dissociates into ions

$Ba(OH)_{2}$ (s)  ⇒ $Ba^{2+}$(aq) + 2$OH^{-}$ (aq)

Total three ions are produced by $Ba(OH)_{2}$

One ion =$Ba^{2+}$

Two ions = $OH^{-}$
