It is an ionic compound.

Table salt = NaCl



Surrounded by molecules of water, oxygen end of water, as water is slightly polar and the oxygen end of the water molecule is slightly negative in charge.


Also surrounded by the polar water molecule, but the hydrogen end(s), as the hydrogen end(s) are slightly positive in charge.

Baking soda is amphoretic, acts like an acid and a base. Soluble, but not nearly as soluble as an ionic compound. Contains a polyatomic ion, CO3.
