Investigating the Copper Content of Brass

This lab extends knowledge of the electromagnetic spectrum, spectrometry and colorimetry. It uses Beer's law and generation of a calibration curve to determine the copper content of a sample of brass. Students are expected to correlate a color spectrum of a metal ion in solution with electron transitions.

Featured Equipment

Colorimeter and Turbidity

Wireless Colorimeter & Turbidity Sensor

This sensor can function as a turbidimeter or colorimeter and is capable of measuring absorbance and transmittance at six different wavelengths.


Wireless Spectrometer (VIS)

Measure intensity, absorbance, transmittance across the visible spectrum, and fluorescence at 405nm and 500nm.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
