Select all ionic compounds in which the number of anions present is three.
ammonium sulfite
ammonium perchlorate
cadmium phosphate
ammonium iodate
ammonium sulfate
barium bromide
none
How can u tell???
I would start with writing the chemical formulas. For instance, barium bromide BaBr2
it has three ions.
I will be happy to critique your work.
How about doing your own homework
To determine which compounds have three anions present, you need to identify the ions in each compound and count the number of anions. Anions are negatively charged ions, so you are looking for compounds with three negatively charged ions.
Let's go through each compound and identify the ions:
1. Ammonium sulfite: The ions in this compound are ammonium (NH4+) and sulfite (SO3^2-). There is one anion present.
2. Ammonium perchlorate: The ions in this compound are ammonium (NH4+) and perchlorate (ClO4-). There is one anion present.
3. Cadmium phosphate: The ions in this compound are cadmium (Cd^2+) and phosphate (PO4^3-). There are three anions present.
4. Ammonium iodate: The ions in this compound are ammonium (NH4+) and iodate (IO3-). There is one anion present.
5. Ammonium sulfate: The ions in this compound are ammonium (NH4+) and sulfate (SO4^2-). There are two anions present.
6. Barium bromide: The ions in this compound are barium (Ba^2+) and bromide (Br-). There is one anion present.
Based on the analysis, Cadmium phosphate is the only compound with three anions present. Therefore, the correct answer is "cadmium phosphate."
