Determining the Copper Content in Brass

Introduction

Brass is an interesting metal that has a wide variety of uses. It is a good example of how elements can be combined to produce a new solid substance with a collection of properties that take advantage of the best, or desired, properties of the individual elements.

Brass is a member of the family of solid substances called alloys. An alloy, simply put, is a mixture of two or more solid elements. A mixture of molten copper and zinc is the simplest form of brass. Commercial forms of brass may also contain small amounts of other elements.

Objectives

The objective of this investigation is to determine how much copper is in a sample of brass. By treating a brass sample with nitric acid, the neutral atoms will be converted to ionic form, which allows for easier analysis.
