QUESTION 4 Using the solubility rules from Table 6-1 of your lab manual, fill out the expected results when the starting materials in the chart below react. Place a "P" in the box if you expect a precipitate to form between two starting materials, "g" if you expect a gas to form, and "NR" if you think no reaction will occur. If the product is slightly soluble put a "p*". An example is shown below. Example: A P is in the top left cell where Rb2504 and AgNO3 intersect because when these starting materials react, you get the following equations. Molecular Equation: Rb2SO4(a 2 AgNo3(a)2 RbNO3(a+Ag2504(s) Net lonic Equation: 2 Ag (aq) + S042-(aq)Ag2504(s) Since a solid/precipitate is formed as a product, a P has been written in the appropriate cell these starting materials intersect. Starting Materials Rb2504 Cs3PO4 AgNO3 P NH4CI P SrBr2

Explanation / Answer

Molecular Equation:

Cs3PO4 (aq) + 3 AgNO3 (aq) -------> Ag3PO4 (s) + 3 CsNO3 (aq)

Net Ionic Equation:

PO43- (aq) + 3 Ag+ (aq) --------> Ag3PO4 (s)

Molecular Equation:

Rb2SO4 (aq) + 2 NH4Cl (aq) --------> 2 RbCl (aq) + (NH4)2SO4 (aq)

The reactants and the products are all soluble and easily ionize; this is a simple double displacement reaction and hence, apparently no reaction (NR) takes place.

Molecular Equation:

Cs3PO4 (aq) + 3 NH4Cl (aq) -------> (NH4)3PO4 (aq) + 3 CsCl (aq)

The reactants and the products are all soluble and easily ionize; this is a simple double displacement reaction and hence, apparently no reaction (NR) takes place.

Molecular Equation:

Rb2SO4 (aq) + SrBr2 (aq) --------> 2 RbBr (aq) + SrSO4 (s)

Net Ionic Equation:

SO42- (aq) + Sr2+ (aq) -------> SrSO4 (s)

Molecular Equation:

2 Cs3PO4 (aq) + 3 SrBr2 (aq) -------> Sr3(PO4)2 (s) + 6 CsBr (aq)

Net Ionic Equation:

2 PO43- (aq) + 3 Sr2+ (aq) --------> Sr3(PO4)2 (s)
