How to distinguish the flame reactionThe flame reaction was a reaction in which certain metals or their compounds caused the flame to show a special color when burned in a colorless flame. It could be distinguished by observing the color of the flame. The flame reaction colors of common metals were: Na yellow, Li purple, K purple, rubidium light purple, calcium brick, Stronghold red, copper green, Ba yellow green. When conducting a flame reaction experiment, a clean platinum wire (or iron wire) was usually used to burn the flame outside the alcohol lamp until the color was the same as before (to prevent impurities on the platinum wire from interfering with the test). Then, the metal wire was dipped in the solution to be tested and burned to observe the color of the flame. Because of the possible use of Na in the production of potash, the solution of potash ions often contained Na ions, and the flame reaction of Na was yellow, which was difficult to distinguish from a small amount of purple. Therefore, when observing the flame color of potash, it was necessary to observe it through a blue-colored glass to eliminate the interference of the flame color of Na. In chemistry, the flame reaction was often used to identify whether a certain metal existed in a compound, such as identifying a solution of NaCl2 and a solution of KCl2. The flame color was yellow for the NaCl2 solution, and the flame color was purple for the KCl2 solution.

Determination of Phosphorus in Flame ReactionThe flame reaction test for the determination of the potassium ion mainly had the following steps: First, the platinum wire was dipped in concentrated sulfuric acid and burned on a colorless flame until it was colorless. Then, the sample was dipped in the colorless flame and burned. Then, the color of the flame was observed through the blue Cobalt Glass. If the flame was purple, it meant that the sample contained the potassium ion. Otherwise, it did not. After the experiment, the platinum wire was dipped in concentrated sulfuric acid and burned until it was colorless. In the flame reaction, because the yellow color of the Na flame might cover up the color of the K flame, it had to be observed with blue Cobalt Glass. This method originated from Bunsen's experiment.

Flame Reaction Experiment of Na SaltThe flame reaction of the salt should not be difficult to do, but it was actually more troublesome because the flame color of the salt was yellow, and the flame of the alcohol lamp was mostly yellow due to the unclean wick of the lamp and the impure alcohol. Even if the flame was almost colorless (light blue), when a new iron wire (or a nickel-based wire, platinum-based wire) was placed on the outer flame, the flame would still be yellow at the beginning. It was difficult to tell whether the flame color was the color of the original alcohol lamp or the color of the salt ion. To clearly see the yellow flame of Na, you can use the following method:
1. Forceps-cotton-alcohol method: Take a small ball of cotton (cotton wool) with a pair of tweezers and absorb a little alcohol (95% alcohol). Squeeze the alcohol on the cotton dry, then dip the cotton in some salt or waterless soda powder (grind it into fine powder) and ignite it.
2. Iron wire method:
- He took a thin iron wire, wiped one end with sandpaper, and burned it on the flame of the alcohol lamp until there was no yellow flame.
- Dip the end of the wire in water and then dip it in some salt or powder of the Na2CO3.
- Light up a new spirit lamp (the wick of the lamp is clean and the spirit is pure).
- The iron wire dipped in the powder of the salt was placed on the tip of the outer flame to burn. At this time, there was a small yellow flame on the tip of the outer flame, which was the salt flame. For students 'experiments, since most alcohol lamps were not clean, it was difficult to see the tip of the flame. Instead, a steel wire stained with salt could be placed in any part of the outer flame where there was a blue flame to burn. If the yellow flame covered the blue flame, it could be considered that the yellow flame was the salt flame.

Materials needed for the flame reaction of potassiumThe materials needed for the flame reaction of potassium were as follows:
1. Platinum wire: used to dip the sample.
2. "Acid: Before the flame reaction, dip the platinum wire in acid and burn it on a colorless flame until it is colorless to remove the interference of impurities on the experiment.
3. Test sample (the solid can be directly dipped in, and the solution of the potassium ion can also be dipped in).
4. Blue Cobalt Glass: Because most of the time, the production of potassium requires the use of Na, and the solution of potassium ions often contains Na ions, and the flame reaction of Na is yellow. Yellow and a small amount of purple cannot be distinguished, so the flame reaction of potassium needs to be observed through blue Cobalt Glass. Blue Cobalt Glass can filter out the yellow light.

Flame reaction experiment of chemical ironThere was no flame reaction on iron, or the frequency of the photon emitted by the iron after being excited had fallen outside the visible light, so the flame reaction experiment on iron could not be carried out.

Flame of Primal Chaos and Blue Moon FlameIn the <<Perfect World>>, the Flame of Primal Chaos and the Blue Moon Flame were extremely special flames.
The Flame of Primal Chaos was not afraid of anything strange. It could suppress all kinds of powerful flames. Shi Hao discovered it when he was exploring the Nine Dragons Coffin. At that time, he discovered that the Blue Lunar Flame was afraid of the Flame of Primal Chaos. Shi Hao even guessed that it was the Flame of Primal Chaos. This ball of flame was the Quasi-Immortal Emperor Flame, the Dao fire left behind by the fallen Quasi-Immortal Emperor of the Emperor Fall Era. It ran through the entire book and was of great help to Shi Hao. It was only at the end that the mysterious veil was unveiled. When Shi Hao and Qi Daolin were exploring the Three Lives Bronze Coffin, they met and subdued it (it was more like it was chosen by it). Qi Daolin knew how powerful it was, and he evaluated it as being able to burn a supreme forbidden character to death. When they arrived at the ancient ruins, this ball of fire played an important role. Shi Hao used the celestial emperor as a furnace and the myriad dao as fire to burn his fleshly body and primordial spirit to forge his true self. If it wasn't for this ball of fire, Shi Hao might have perished in the strange ancient ruins.
The Blue Moon Flame was left behind by True Immortal Blue Moon, who had fallen in the war between the foreign lands. When True Immortal Blue Moon was alive, she was only at the level of a True Immortal, but she had mastered the Reincarnation Nirvana Technique that only Immortal Kings could use. Qing Yi and Yue Chan were her reincarnation bodies. Shi Hao had given Qing Yi the Blue Moon Flame as a kindling to ignite her divine fire. Under normal circumstances, cultivators would use a strange fire from the outside world to ignite their own Dao fire and reach the Divine Fire Realm. The strange fire would leave, but the Blue Moon Flame had perfectly fused with Qing Yi, so she could still use it to fight. When Qing Yi was refining the Blue Lunar Flame, a wisp of True Immortal Blue Moon's remnant thought fused into her divine sense. This caused Qing Yi's attitude towards Shi Hao to change drastically, and she gained a unique understanding of becoming an immortal and comprehending the Dao. She put aside her personal feelings and was able to control her body when she fused with Yue Chan in the later stages. However, due to True Immortal Blue Moon's influence, Qing Yi was obsessed with becoming an immortal, and in the end, she abandoned Shi Hao and headed to the Immortal Domain alone.

Red Flame Star, Blue Flame Star, Green Flame StarPeople usually thought that Mars was red because the surface of Mars was covered with a large amount of iron dioxide (rust). Billions of years ago, the water on Mars and the oxygen decomposed from the water vapor in the atmosphere reacted with the iron element in volcanic eruptions to form iron dioxide. Later, due to the loss of the atmosphere and water, the surface of Mars was exposed to radiation, and the rocks and sand were further oxided. In addition, sandstorms caused red dust to cover the surface of the planet and the atmosphere, so Mars appeared orange from Earth or space. However, the latest photos revealed that the true color of Mars was a complex color spectrum. Large areas were deep blue due to gray-black basaltic sand, which indicated the existence of volcanic activity. There were also areas that had been eroded by water that were lighter in color, and clay and sulfuric minerals showed bright luster. There was no information about the green Martian surface.
