If aqueous solutions of NaF and BaCl2 are combined, what two new compounds could form?
To determine the possible compounds that can form when aqueous solutions of NaF and BaCl2 are combined, we need to identify the potential reactions between the ions present in these solutions.
First, let's consider the dissociation of NaF and BaCl2 in water:
NaF(s) -> Na+(aq) + F^-(aq)
BaCl2(s) -> Ba^2+(aq) + 2Cl^-(aq)
Now, let's examine the possible reactions that can occur between the ions:
1. Na+(aq) + Cl^-(aq) -> NaCl(s)
2. Ba^2+(aq) + 2F^-(aq) -> BaF2(s)
So, when NaF and BaCl2 are mixed, the two new compounds that can form are NaCl and BaF2.
