Which of the following statements is/are true of metal plating?
1) Metals that readily corrode can be protected by the application of a thin coating of a metal that resists corrosion.
2) An object can be plated with metal by making it the cathode in a tank containing ions of the plating metal.
3) An object can be plated with metal by making it the anode in a tank containing ions of the plating metal.

Statement 1 is true because metal plating involves applying a thin coating of a metal that resists corrosion to protect metals that are prone to corrosion.

Statement 2 is also true because metal plating can be achieved by making the object to be plated the cathode in a tank containing ions of the plating metal. This allows the metal ions to be deposited on the surface of the object being plated.

Statement 3 is false because making an object the anode in a plating tank containing ions of the plating metal would cause the object to dissolve and deposit metal ions into the plating solution, rather than depositing metal ions onto the surface of the object.
