Question

determine the name of the ionic compounds listed below with polyatomic ions: 1. nh4cl 2. na2so4 3. k3po4 4. kno3 5. lioh

Explanation:

1. For $NH_4Cl$, the polyatomic ion is $NH_4^+$ (ammonium), so it is ammonium chloride.
2. For $Na_2SO_4$, the polyatomic ion is $SO_4^{2 -}$ (sulfate), so it is sodium sulfate.
3. For $K_3PO_4$, the polyatomic ion is $PO_4^{3 -}$ (phosphate), so it is potassium phosphate.
4. For $KNO_3$, the polyatomic ion is $NO_3^-$ (nitrate), so it is potassium nitrate.
5. For $LiOH$, the polyatomic ion is $OH^-$ (hydroxide), so it is lithium hydroxide.

Answer:

1. Ammonium chloride
2. Sodium sulfate
3. Potassium phosphate
4. Potassium nitrate
5. Lithium hydroxide
