Answer:
Al^3+(aq) + PO4^3-(aq) → AlPO4(s)
Explanation:
Step 1: Data given
potassium phosphate = K3PO4
aluminum chloride = AlCl3
potassium chloride = KCl
aluminum phosphate = AlPO4
Step 2: The unbalanced equation
K3PO4(aq) + AlCl3(aq) → KCl (aq)+ AlPO4(s)
On the left side we have 3x K (in K3PO4), on the right side we have 1x K (in KCl). To balance the amount of K on both sides, we have to multiply KCl (on the right side ) by 3. Now the equation is balanced.
K3PO4(aq) + AlCl3(aq) → 3KCl(aq)+ AlPO4(s)
The net ionic equation, for which spectator ions are omitted - remember that spectator ions are those ions located on both sides of the equation - will look like this
Al^3+(aq) + PO4^3-(aq) → AlPO4(s)
It’s going to be d. a test cross
Answer:
Option D is good to go!
Explanation: as per the reactivity series more reactive substances will react with the counterpart substance.The most reactive substance here is calcium while the least reactive is aluminium, the magnesium comes in between.As per their reactivity, these substances will react with oxygen.
