We test several chloride salts for their flame test colors. We then determine the identity of two unknowns via flame test.

For those asking why cotton swab instead of platinum (or nichrome) wire, and those asking why H2O instead of HCl: Cotton swabs are cheaper than platinum wire. You use HCl to clean the platinum wire so that it is not contaminated, but in this case, because he throws away every used cotton swab, there is no need to clean it. The water is for wetting the cotton so that the salt sticks onto the swab.

Errrrg! Both unknowns look like sodium! Probably my laptop. I did note that sample #1 appeared to burn brighter than #2, which I also noticed with the sodium/barium flames. Barium seems to emit less visible color as well. Would be interested to see the flames' ultra and infra signatures. With neon (actually referring to just one color) signs, colors are due to gases of the same elements we watched burn in the video, sealed in glass tubes, with embedded wire electrodes. What I cannot find is the type of wire used. Would some metals react differently to the trapped gas? Do specific metals work best with certain gases, or am I over-analyzing? Colors near the violet spectrum, seem dim to my naked eyes. When I look at neon signs, greens and blues tend to do the same thing. If the sign is heavy on yellow-to-reds, the greens and blues seem to recede. I know there are more colors than most humans can discern. I'd love to view neon tubes' infra-ultra spectrums. How do such colors appear to others in this forum? I presume color-blindness would make them look quite different, but how about those with wider spectrums than mine? Do we all see colors the same way? Thank you.

Aayushman Singh yes but there is probably sodium somewhere in the mix either from the q-tip, the water, or even the soap used to clean the flask. A small amount of sodium can over power most colors which is why open flames are usually yellow. So to get the Green color you must look at the flam through colbalt glass. The Glass absorbs the yellow color and leaves a green color.

May someone please explain to me the significance of doing flame tests (like what is its purpose)? I'm doing a science project on this and I found this topic quite interesting, but quantum chemistry (I think that's what it is) is a whole knew lesson that I need to learn. May someone also explain how you can identify an unknown metal-salt just by the color of the flame? Because there are a number of different metals that give off the same color (or hard to distinguish shades of that color)
@Ichigo1127788 жыл бұрын
+HeyItzCho Great questions! The first thing to remember is that light is a form of electromagnetic energy. All electromagnetic energy has it's own frequency. Scientists use a spectrometer when doing flame test in order to record the electromagnetic frequency. For example, red light has a frequency of 400-484 THz. Even if two metals give off red light, the frequency would be different.

When I burn strontium, the flame is red (using a metal tip of stainless steel, and dilute HCl solution). I make my 'swabs' from a short piece of wood, then hammer a thin steel nail into the end of it, cut the head off with a pliers, and if neccessarry I'll sharpen the tip. Then I coat the wood with aluminium foil. Makes for a nice little tool. Remember to heat the steel tip in the bunsen flame for a while, to get rid of excess iron ions. Many years ago, I used solid metal salts, dipping in water, like in this video, but this tends to be 'overkill' for the students, as salts melt and drip into the burner flame. Since we here in Norway use burners with a tank, not bunsen, that is very annoying for me as a teacher, as I have to clean the burner heads after class. So instead I now prepare dilute HCL solutions of the salts, and just dip the tip of my tool in them. These solutions do not have to be very concentrated, and I can adjust the concentration during preparation to get clear colors in the burner flame. This also makes for at better guessing games when trying to determine an unknown salt, as most of the solutions become colorless at low concentrations (maybe not cupper chloride, but it is not easy to camoflage that color anyhow, and that one should maybe be memorized through multiple choice / open question in stead of flame test comparishon). I prepare the salt solutions in regular heat resistant (borocilicate) test tubes, and can then ask the students to pour a little from each of these into their own porcelain palettes, like these ones from aliexpress: www.aliexpress.com/item/32857062305.html Also, for those interested in this topic, buring iron oxide adds a little bit of 'spark' to the equation, and is always fun to use. If I have some time on my hands, I'll post a link to how I do this. Stay tuned. I'll try it out tomorrow, but have a busy schedule.
