Which solutions react to produce an insoluble compound?
??????(????)+LiCl(????)?
LiCl(????)+NaNO3(????)?
NaCl(????)+AgClO3(????)?
KNO3(????)+AgClO3(????)?
The Correct Answer and Explanation is :
To determine which solutions react to produce an insoluble compound, we need to look at solubility rules and predict whether a precipitate will form.
- ??????(????) + LiCl(????)
- This reaction will depend on the identity of the first compound. If it’s an ionic compound that forms an insoluble combination with LiCl, a precipitate could form. However, without knowing the first reactant, it’s unclear.
- LiCl(????) + NaNO3(????)
- Both lithium chloride (LiCl) and sodium nitrate (NaNO3) are soluble in water. There are no insoluble products when these two compounds mix. Therefore, no precipitate forms in this reaction.
- NaCl(????) + AgClO3(????)
- Sodium chloride (NaCl) and silver chlorate (AgClO3) are both soluble in water. They do not form an insoluble compound when combined. No precipitate is expected here either.
- KNO3(????) + AgClO3(????)
- Potassium nitrate (KNO3) and silver chlorate (AgClO3) are both soluble in water. There is no potential for the formation of an insoluble compound between these two.
From these four reactions, none will result in an insoluble compound because all the involved salts are soluble in water. To summarize:
- For a reaction to produce an insoluble compound (a precipitate), at least one of the products must be insoluble according to solubility rules. Common examples of insoluble compounds include silver chloride (AgCl), barium sulfate (BaSO4), and calcium carbonate (CaCO3).
- Solubility rules state that most salts of sodium (Na+), potassium (K+), ammonium (NH4+), and nitrates (NO3-) are soluble. Therefore, the reactions listed, involving Na+, Li+, K+, and NO3-, will not lead to the formation of an insoluble compound.
