A student adds sodium hydroxide (NaOH to the solution at equilibrium. In one to two sentences, describe and explain any changes to the solution that the student will observe.

In one to two sentences, explain why metal is often used for making wire and the properties that make metal useful.

The student will observe an increase in the pH of the solution and the formation of a precipitate as the sodium hydroxide reacts with the ions in the equilibrium solution.

Metals are often used for making wire because they are ductile, allowing them to be easily shaped into thin, flexible wires. Additionally, metals are good conductors of electricity and heat, making them useful for a variety of applications.
