Flame tests are used to identify the presence of a relatively small number of metal ions in a compound. Not all metal ions give flame colors. For Group 1 compounds, flame tests are usually by far the easiest way of identifying which metal you have got.
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)
Answer:
If you meant Atoms then the answer is false
