Solubility Rules: Sample Problems

Try each one on paper first. Only then reveal the solution — reading a worked answer you never attempted teaches you almost nothing.

1. 1. Predict the precipitate when AgNO₃(aq) is mixed with NaCl(aq).

2. 2. Will a precipitate form when K₂SO₄(aq) meets Ba(NO₃)₂(aq)?

3. 3. Mix NH₄Cl(aq) with NaNO₃(aq). What happens?

Start with the 'always soluble' list. If both products are on it, no reaction happens — and that's a real answer worth points.
