USING THE SOLUBILITY RULES



Solubility Rules Worksheet

1. Classify each of the substances as being soluble or insoluble in water.

|KBr = |silver acetate = |

|PbCO3 = |copper (II) sulfide = |

|BSO3 = |Mg3(PO4)2 = |

|zinc hydroxide = |KOH = |

|sodium acetate = |NiCl2 = |

|silver iodide = |NH4OH = |

|cadmium (II) sulfide = |Hg2SO4 = |

|zinc carbonate = |PbI2 = |

| |. |

2. Identify the two new compounds which form if the solutions, as suggested by the following table, were mixed. CIRCLE the names of the compounds which would precipitate from the solutions.

| |KBr |Na2CO3 |CaS |NH4OH |

| | | | | |

|AgNO3 | | | | |

| | | | | |

|BaCl2 | | | | |

| | | | | |

|Al(NO3)3 | | | | |

| | | | | |

|CuSO4 | | | | |

3. Classify each of the substances as being soluble or insoluble in water.

|potassium bromide – sol |silver acetate – sol |

|lead (II) carbonate – insol |copper (II) sulfide – insol |

|barium sulfate – insol |Mg3(PO4)2 – insol |

|zinc hydroxide – insol |KOH – sol |

|sodium acetate – sol |NiCl2 - sol |

|silver iodide – insol |NH4OH – sol |

|cadmium (II) sulfide – insol |Hg2SO4 – insol |

|zinc carbonate – insol |PbI2 – insol |

| |. |

4. Identify the two new compounds which form if the solutions, as suggested by the following table, were mixed. CIRCLE the names of the compounds which would precipitate from the solutions.

| |KBr |Na2CO3 |CaS |NH4OH |

| |AgBr + KNO3 |NaNO3 + Ag2CO3 |Ca(NO3)2 + Ag2S |AgOH + NH4NO3 |

|AgNO3 | | | | |

| |KCl + BaBr2 |NaCl + BaCO3 |CaCl2 + BaS |Ba(OH)2 + NH4Cl |

|BaCl2 | | | | |

| |AlBr3 + KNO3 |NaNO3 + Al2(CO3)3 |Ca(NO3)2 + Al2S3 |NH4NO3 + Al(OH)3 |

|Al(NO3)3 | | | | |

| |CuBr2 + K2SO4 |Na2SO4 + CuCO3 |CuS + CaSO4 |(NH4)2SO4 + Cu (OH)2 |

|CuSO4 | | | | |
