- aluminum nitrate
- ammonium sulfate
Transcript text: Classify each of the compounds as soluble or not soluble:
$\square$ manganese(II) carbonate
$\square$ aluminum nitrate
$\square$ ammonium sulfate
Solution
Solution Steps
Step 1: Determine Solubility Rules for Manganese(II) Carbonate
Manganese(II) carbonate, \( \text{MnCO}_3 \), is a carbonate compound. According to solubility rules, most carbonate compounds are not soluble in water, except for those of alkali metals and ammonium. Since manganese is not an alkali metal, manganese(II) carbonate is not soluble.
Step 2: Determine Solubility Rules for Aluminum Nitrate
Aluminum nitrate, \( \text{Al(NO}_3\text{)}_3 \), is a nitrate compound. According to solubility rules, all nitrate (\( \text{NO}_3^- \)) compounds are soluble in water. Therefore, aluminum nitrate is soluble.
Step 3: Determine Solubility Rules for Ammonium Sulfate
Ammonium sulfate, \( \text{(NH}_4\text{)}_2\text{SO}_4 \), contains the ammonium ion (\( \text{NH}_4^+ \)). According to solubility rules, all compounds containing the ammonium ion are soluble in water. Therefore, ammonium sulfate is soluble.
