- a substance can be identified after the melting point because it is a specific physical characteristic
- melting points knowledge is necessary for technology
A chemist uses lab equipment, such as beakers, graduated cylinders, lab googles, etc.
A chemist working in a laboratory will use titration, which is an analytical process to measure the amount of a substance dissolved in liquid. Normally the chemist would be described as an Analytical Chemist.
A melting point is physical because it uses the measures of physical changes.
A forensic chemist may use equipment such as microscopes, spectrophotometers, gas chromatographs, mass spectrometers, and infrared spectrometers to analyze evidence collected from crime scenes. These tools help them identify and analyze substances present in samples like drugs, toxic chemicals, and gunshot residue.
aspirator is used in measuring a substances
Filtration takes advantage of differences in particle size to separate substances from a mixture, while distillation uses differences in boiling points to separate substances based on their volatility. Both processes rely on physical properties of the substances being separated to achieve purification.
