Identification of metals through element flame test lab, using flame test virtual lab techniques.
Flame test simulation is used to identify metals in their salts as each metal shows a characteristic color when immersed in Bunsen flame.
Become proficient at running the identification of flame tests.
Flame test chemistry is a qualitative identification test that is used to detect the presence of metal ions in their salts either in their powder form or solutions.
Flame test is not the sole test that is used for the identification of metals.
However, it is a confirmatory test for some metals, especially group 1 metals.
In a flame test experiment, when atoms or ions are exposed to heating, electrons gain energy to be excited from their normal energy levels to higher energy levels.
Afterward, the electrons jump back to their original energy levels; either in one in several steps, releasing energy as electromagnetic radiations.
Each of these steps is represented by the emission of a specific amount of energy in the form of light that corresponds to a particular wavelength.
Hence, a spectrum of lights can be produced, some of which are within the visible region of the spectrum that will combine forming the light that we can see, creating the distinctive colored flames chemistry observed in flame tests.
The space between different energy levels within an atom represents the transition sizes that would occur for the electrons, and consequently the energy and wavelengths of the electromagnetic radiation emitted.

Performing flame test virtual lab for different metals to identify them according to their corresponding colors that are observed upon immersion of sample into the Bunsen flame.
The corresponding flame test colors of some metals are shown below:
I love the idea of virtual labs. It's gonna be something that takes our R&D and work in labs to another level. And I look forward to seeing what PraxiLabs can do with it.

Although there are now several vendors offering virtual reality software for physics labs, there is only one that offers a realistic, I feel like I’m in a real lab solution: PraxiLabs.

PraxiLabs offered my students a chance to actively engage with the material. Instead of watching videos on a topic, they could virtually complete labs and realize the practical applications of class topics. This is a quality alternative to in-person labs.

With the onset of the COVID-19 pandemic, we found ourselves in a situation that forced us to act quickly to find the best solution available to provide our students with a quality molecular genetics laboratory experience.
