Write the formulas of the compounds formed by NH4+ with the following anions: NO3−, HCO3−, SO42−, HPO42−.
Express your answers as chemical formulas separated by commas. Use the given order of anions.
match so the compound is zero charge as in
NH4NO3
NH4HCO3
(NH4)2SO4
(NH4)2HOI4
etc.
The formulas of the compounds formed by NH4+ with the given anions are as follows:
NH4NO3,
NH4HCO3,
NH42SO4,
NH4HPO4
To determine the formulas of compounds formed by NH4+ with the given anions, we can simply combine the charges to achieve a neutral compound.
1. NH4+ with NO3−:
The compound formed is ammonium nitrate.
NH4+ + NO3− = NH4NO3
2. NH4+ with HCO3−:
The compound formed is ammonium bicarbonate.
NH4+ + HCO3− = NH4HCO3
3. NH4+ with SO42−:
The compound formed is ammonium sulfate.
NH4+ + SO42− = (NH4)2SO4
4. NH4+ with HPO42−:
The compound formed is ammonium hydrogen phosphate.
NH4+ + HPO42− = NH4HPO4
So, the formulas of the compounds formed are NH4NO3, NH4HCO3, (NH4)2SO4, and NH4HPO4, respectively.
