Did the reaction occur?​​​Classification of Reaction? ​

Answer 1

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: PO₄^3- and Ni²⁺

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