Abstract
A module for laboratory practice in quantitative analytical chemistry subject has been developed. The method uses digital image colorimetry as a basis for low-cost spectrophotometry analysis. Reduction-oxidation reaction of silver nanoparticle and mercury (II) ion was used as a case study for the colorimetric experiment. The yellow color of silver nanoparticle was faded linearly to colorless with the addition of mercury ion as an analyte. The color change was then recorded with a digital camera and processed through computer software to extract the color information in the form of Red, Green and Blue. The module of laboratory practice was then applied to students in chemical education study program. The gain of the learning process was measured using pre-test and post-test. The results of the study indicate that the students were able to understand the concept of spectrophotometry by using the developed module of digital image colorimetry. Therefore, we conclude that laboratory practice of digital image colorimetry is applicable as an alternative to the traditional spectrophotometry.
