hydrogen added to an ion changes the charge by +1 Think proton.

Add hydrogen to an ion Example: carbonate: CO32- hydrogen carbonate: HCO3- (old name = bicarbonate)

What is hydrogen phosphate? HPO42-

What is HSO2- ? hydrogen hyposulfite

lithium nitrate Cation: Li+ Anion: NO3- Compound: LiNO3

calcium hydroxide Cation: Ca2+ Anion: OH- Compound: Ca(OH)2

ammonium sulfate Cation: NH4+ Anion: SO42- Compound: (NH4)2SO4

Try these: sodium carbonate barium phosphate magnesium sulfate

Answers sodium carbonate = Na2CO3 barium phosphate = Ba3(PO4)2 magnesium sulfate = MgSO4

Ca(NO3)2 Cation: calcium Anion: nitrate Compound: calcium nitrate

FeCrO4 Cation: iron(???) Total neg/cations = 2/1 So cation: iron(II) Anion: chromate Compound: iron(II) chromate

Try these: KClO3 NH4OH Sr3(PO4)2 Sn(ClO4)2

Answers: KClO3 = potassium chlorate NH4OH = ammonium hydroxide Sr3(PO4)2 = strontium phosphate Sn(ClO4)2 = tin(II) perchlorate
