Multiple Choice
Consider the reaction: 3Co2+(aq) + 6NO3(aq) + 6Na+(aq) + 2PO43-(aq) → Co3(PO4) 2(s) + 6Na+(aq) + 6NO3(aq)
Identify the net ionic equation for this reaction.
A) Na +( aq) + NO 3 −( aq) → NaNO 3( aq)
B) 3Co 2+( aq) + NO 3 −( aq) + Na +( aq) + 2PO 4 3−( aq) → Co 3(PO 4) 2( s) + NaNO 3( aq)
C) 3Co 2+( aq) + 6NO 3 −( aq) + 6Na +( aq) + 2PO 4 3−( aq) → Co 3(PO 4) 2( s) + 6NaNO 3( aq)
D) 3Co 2+( aq) + 2PO 4 3−( aq) → Co 3(PO 4) 2( s)
E) None of these choices are correct.
