Why does KCl potassium chloride make high energy purple flames and SrCl2 strontium chloride makes low energy red flames?
potassium and strontium both absorb heat energy and this makes electrons(e-) jumpfrom the base (normal) energy level to a higher energy level. The base is NOT etactly the same for these 2 elements and neither are the higher levels. This transition absorbs different amounts of energy. This absorbed energy is released as various electromagnetic waves when the e- transition back to the lower (base) energy levels. Different amount or energy are released which correlates to different colors of the electromagnetic spectrum.

What salts produce lilac flames?
Lithium salts, such as lithium chloride or lithium carbonate, are known to produce lilac flames when burned. This color results from the excitation of lithium ions in the flame.
Which elements may be excited when heating sodiumlithiumbariumpotassiumstrontiumand calcium using a Bunsen burner flame?
When heating sodium, lithium, barium, potassium, strontium, and calcium with a Bunsen burner flame, the heat energy can excite the electrons of these alkali and alkaline earth metals. This excitation can lead to the emission of light as the excited electrons return to their ground state, producing characteristic flame colors. For example, sodium emits a bright yellow flame, lithium produces a red flame, and potassium gives a lilac color. Barium and strontium emit green and red flames, respectively, while calcium produces an orange-red flame.
Two of this elements compounds burn with a red flame and are used in fireworks and signal flares?
Strontium and lithium are two elements whose compounds burn with a red flame and are commonly used in fireworks and signal flares. The strontium compound strontium nitrate and the lithium compound lithium carbonate are examples of substances that contribute to the red color in pyrotechnics.
What are 4 What are facts about strontium?
1) Strontium bursts into flames when it is exposed to air. 2) It was discovered in Scotland. 3) It's used in fireworks and toothpaste. 4) Strontium is a soft, silvery metal. 5) Strontium titanate is very soft but has an extremely high refractive index and an optical dispersion greater than that of diamond. (It bends and separates light)
What compounds create red and purple fireworks?
The addition and combination of various powdered metals and minerals added in various combinations produce the colors that we see. Copper, magnesium, iron powders, sulphurs , and many other elements all combine to create the palette of colors pyrotechnical artist's employ for our pleasure. Copper is used to make the blue colour of fireworks. Although copper produces a green flame in a laboratory flame test, the use of copper in relatively low temperature flames and in the presence of chlorine produces CuCl+ ions that give out bright blue emission lines at moderately flame temperatures. Caesium can also be used, but this is much too expensive for normal use. In general, the difficulty of producing blue flames in fireworks means that their presence in a firework display is is a reasonable indicator of the expense and quality of the display. magnesium gives a brilliant white light. Copper, although rare because of the dangers of reacting with potassium chlorate to produce highly explosive copper sulfate, can be burned to produce a brilliant blue light.
What colour flame do you get when you burn strontium chloride?
The flame test for strontium - a strong red color.
What two chemicals are in yule logs that make the flame red and green?
The RED can be either Strontium Nitrate or Bismuth nitrate, and the GREEN is either Barium chloride or Boric Acid. Be careful with any/all nitrates around children as they can be poisonous.
What do you need to make different color fires?
To make different color fires, you can use specific chemicals or materials that produce colored flames when burned. For example, adding copper chloride can create blue flames, while strontium chloride can produce red flames. It's important to use caution when working with these materials and to be aware of any safety guidelines.
What salts produce lilac flames?
Lithium salts, such as lithium chloride or lithium carbonate, are known to produce lilac flames when burned. This color results from the excitation of lithium ions in the flame.
What elements can be excited using a Bunsen burner?
Elements such as sodium, potassium, lithium, calcium, strontium, and barium can be excited using a Bunsen burner to emit characteristic colored flames. The color produced is unique to each element due to the energy levels of the electrons transitioning back to their ground state.
What happens when mix potassium to hydrochloric acid?
When potassium is mixed with hydrochloric acid, a chemical reaction occurs producing potassium chloride and hydrogen gas. The reaction is exothermic, meaning it releases heat and potentially sparks or flames. It is important to handle this reaction carefully in a controlled environment due to the potential hazards.
What color flames do you get when you burn the elements?
Manganese (II) Chloride - pale yellow-green strontium chloride - red sodium chloride - bright yellow-orange lithium chloride - red copper (II) chloride - bright green calcium chloride - yellow-red boric acid - nothing
How can I learn how to color a flame effectively?
To effectively color a flame, you can learn by experimenting with different chemicals that produce different colors when burned. Some common chemicals used for coloring flames include copper chloride (green), strontium chloride (red), and sodium chloride (yellow). It is important to follow safety precautions and conduct experiments in a well-ventilated area. Additionally, you can find tutorials and guides online that provide step-by-step instructions on coloring flames. Practice and patience are key to mastering this skill.
What effects would you expect on the flame colors if these compounds were chlorides instead of nitrates?
If the compounds were chlorides instead of nitrates, you would likely see a different color flame due to the different metal cations present. For example, potassium chloride would produce a lilac flame, while strontium chloride would produce a red flame. Each metal cation emits a characteristic color when ions are heated.
Why do yule logs burn red and green?
Some Yule logs that are available commercially have green and red flames when they burn. The chemicals that cause the colored flames are barium and strontium.
