Barium produces a light or apple green flame when held in a hot clean burning gas flame.
it could be confused with the different green flames produced by copper, boron, molybdenum, antimony, tellurium, thallium, phosphorus and others.
Strontium is the element that turns a flame carmine red when it is burned. When strontium is present in a flame, it imparts its characteristic red color due to the emission of specific wavelengths of light.
Copper (II) nitrate burns with a blue-green flame, characteristic of copper compounds.
Potassium compounds other than borates, phosphates, and silicates. Masked by sodium or lithium.
The apple is reacting with oxygen in the air, leading to a process called oxidation. This causes the exposed part of the apple to turn brown due to a chemical reaction that breaks down the apple's pigments.
Copper is a metal that turns green when oxidized.
Oxygen (O2)
Sodium (Na)
Strontium is the element that turns a flame carmine red when it is burned. When strontium is present in a flame, it imparts its characteristic red color due to the emission of specific wavelengths of light.
Oxygen turns copper green.
When burned, copper produces a green flame due to the presence of copper compounds, often creating a vibrant display reminiscent of envy or greed. This phenomenon is commonly utilized in fireworks and flame tests in chemistry to identify copper ions. The association of the color green with greed is largely symbolic, stemming from cultural interpretations of green as the color of money and jealousy.
Phosphorus is an element that turns white when exposed to air. When pure, it is a colorless and transparent waxy solid.
Potassium although sometimes it can look purple
the color of mercury is gray it has no color
Lithium turns red in flame tests.
Nearly all are like that, green at first.
Copper (II) nitrate burns with a blue-green flame, characteristic of copper compounds.
The Statue of Liberty is made out of a copper element. When copper erodes or is exposed to oxygen progressively, it turns green.
