write a balanced equation for the reaction of aluminum with platinum and chloride.
To write a balanced equation for the reaction of aluminum with platinum and chloride, we need to determine the chemical formulas of the compounds involved.
Aluminum is a metal with the chemical symbol Al. Platinum is also a metal with the chemical symbol Pt. Chloride is an anion, meaning it carries a negative charge, with the chemical symbol Cl-.
Since aluminum is a metal, it tends to lose electrons and form positive ions. Platinum, as a transition metal, can have variable charges but commonly has a charge of +2. Chloride, being an anion, carries a charge of -1.
Therefore, we can write the formulas for the compounds as follows:
Aluminum: Al
Platinum: Pt
Chloride: Cl-
Now, let's try combining these compounds to form the balanced equation.
Since platinum has a +2 charge and chloride has a -1 charge, we need two chloride ions (2Cl-) to balance the charge of one platinum ion (Pt2+). This gives us:
2Cl- + Pt2+ --> PtCl2
Now, let's add the aluminum. Since aluminum has a +3 charge and chloride has a -1 charge, we need three chloride ions (3Cl-) to balance the charge of two aluminum ions (2Al3+). This gives us:
2Al3+ + 3Cl- + Pt2+ --> 2Al3+ + PtCl2
Finally, we can simplify the equation by canceling out the common ions on both sides:
Pt2+ + 3Cl- --> PtCl2
So, the balanced equation for the reaction of aluminum with platinum and chloride is:
2Al + PtCl4 → 2AlCl3 + Pt
