Question

Reduce the following equation to a net ionic equation:

2 upper N a superscript plus, plus upper S upper o subscript 4 superscript 2 minus, plus upper B a superscript 2 plus, plus 2 upper C l superscript minus right arrow 2 upper N a superscript plus, plus 2 upper C l superscript minus plus upper B a upper S upper O subscript 4.

2 upper N a superscript plus, plus 2 upper C l superscript plus right arrow 2 upper N a upper C l.

Upper S upper O subscript 4 superscript 2 minus, plus 2 upper B a superscript 2 plus, right arrow upper B a upper S UPper O subscript 4.

2 upper N a superscript plus, plus upper S upper O subscript 4 superscript 2 minus, right arrow upper N a subscript 2 upper S upper O subscript 4.

Answer 1

Start with the full ionic equation:
2 Na+ (aq) + SO4 2- (aq) + Ba2+ (aq) + 2 Cl- (aq) → BaSO4 (s) + 2 Na+ (aq) + 2 Cl- (aq)

Cancel the spectator ions (2 Na+ and 2 Cl-). The net ionic equation is:
Ba2+ (aq) + SO4 2- (aq) → BaSO4 (s)
