Explanation / Answer

Solution:-

Molecular equation:-

2 Na3Po4(aq) + 3 NiCl2(aq) = Ni3(Po4)2(s) + 6 NaCl(aq)

Complete Ionic Equation:

6Na+ (aq) + 2PO4 3- (aq) + 3Ni 2+(aq) + 6Cl- (aq) 6Na + (aq) + 6Cl-(aq) + Ni3(PO4)2(s)

Net Ionic Equation:

2PO4 3- (aq) + 3Ni 2+ (aq) Ni3(PO4)2(s)

Formulas of the possible products:

1. Ni3(PO4)2(s) = Nickel(II) phosphate

2. NaCl = Sodium Chloride

Observation and Evidence of Reaction: is a solid precipitate is formed Nickel(II) phosphate

Spectator Ions: Na+ and Cl-

Reacting Ions: PO43- and Ni2+

Yes the reaction occurs and the type of reaction is "Double Replacement reaction".
