Investigating the Copper Content of Brass (Colorimeter)

This lab extends knowledge of the electromagnetic spectrum, spectrometry and colorimetry. Students use Beer's law and generate a calibration curve to determine the copper content of a sample of brass. Students are expected to correlate the 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.

Spectrometer

Wireless Spectrometer (Vis)

Measures intensity, absorbance, and transmittance across the visible spectrum. Includes fluorescent excitation at 405nm and 500nm.

Support

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.
