Question

Solid ammonium nitrate (NH4NO3) and solid calcium chloride were placed in water and the mixture was stirred. What is the precipitate?

1. No precipitate is expected. 2. NH4Cl
3. Ca(NO3)2
4. NH4NO3
5. CaCl2

Answer 1

1. No precipitate is expected when ammonium nitrate and calcium chloride are dissolved in water, because both of the possible products, ammonium chloride and calcium nitrate, are soluble according to standard solubility rules.

Step-by-step explanation:

When solid ammonium nitrate (NH4NO3) and solid calcium chloride (CaCl2) are placed in water, you would first consider the possible double-replacement products: ammonium chloride (NH4Cl) and calcium nitrate (Ca(NO3)2). To determine if a precipitate forms, you should refer to solubility rules.

According to these solubility rules, compounds containing the ammonium ion (NH4+) and nitrates (NO3-) are generally soluble in water. Since both ammonium chloride and calcium nitrate are soluble, we would not expect any precipitate to form. Thus, the correct answer is: No precipitate is expected.
