Question

Can you help me with the net ionic equation for these chemical reactions?

CaCl2+K3PO4=Ca3(PO4)2+KCl

Answer 1

we have below given equation

3 CaCl2 (aq) + 2 K3PO4 (aq) --> 3 Ca3(PO4)2 (s) + 6 KCl (aq)

Total ionic equation is

Spectator ions should not be removed here. Spectator ions are part of total ionic equation

3 Ca2+ (aq) + 6 Cl- (aq) + 6 K+ (aq) + 2 PO43- (aq) --> 3 Ca3(PO4)2 (s) + 6 K+ (aq) + 6 Cl- (aq)

Spectator ions should be removed now. Spectator ions are not part of total ionic equation

After removing Spectator ions, net ionic equation is:

3 Ca2+ (aq) + 2 PO43- (aq) —> Ca3(PO4)2 (s)

Answer:

3 Ca²⁺ (aq) + 2 PO₄^3- (aq) —> Ca₃(PO₄)₂ (s)
