Question
Reaction 1 Barium solution and ammonium carbonate. Example-Barium solution would be from a solution of a barium and chloride compound. Ba is a earth alkali metal therefore it's oxidation state in a compound is +2. Chlorides have an oxidation state of -1. To cancel out the charge there needs to be two chloride ions for every one barium ion and the formula for barium chloride would be BaCl2 Write a balanced chemical equation for barium chloride and sodium carbonate: BaCl2 + (NH4)2CO3 Write the Net ionic equation for this reaction. If there is a precipitate, circle it in the net ionic equation. Reaction 2- Barium solution and sodium phosphate. Write the Net ionic equation for this reaction. If there is a precipitate, circle it in the net ionic equation. 2-Explanation / Answer
1. Balanced reaction
BaCl2 + (NH4)2 Co3--------------> BaCo3 + 2NH4Cl
Net ionic equation
Ba2+ + Co3-2 ---------> BaCo3
the precipitate will be BaCo3
2. Balanced reaction
3BaCl2 + 2Na3Po4 -----------> 6NaCl + Ba3(Po4)2
net ionic reaction
3Ba2+ + 2Po4-3 --------------> Ba3(Po4)2
