Lithium flame colours are red or crimson when burned in a flame. This is due to the presence of lithium ions emitting light at specific wavelengths as they are heated in the flame. The colour can vary slightly depending on the temperature of the flame and other factors.

What alkali metal produces violet flame when mixed with water?
Lithium is the alkali metal that produces a violet flame when mixed with water. This color arises due to the excitation of electrons in the lithium atoms, leading to the emission of light in the violet part of the spectrum.
Which group of s block elements show distinctive colors when they interact with fire?
Alkali metals, such as lithium, sodium, and potassium, are s block elements that display distinctive colors when they interact with fire. For example, lithium burns with a bright red flame, sodium produces a yellow flame, and potassium results in a lilac-hued flame.
What is the major difference between the colours of flames produced by alkali metal with that of calcium when performing flame tests?
The major difference is the color of the flame produced. Alkali metals typically produce a lilac or purple flame, while calcium produces an orange-red flame. This difference is due to the unique electronic configurations and energy levels of the atoms in each element.
What alkali metal reacts most slowly with water?
Among the alkali metals, lithium reacts most slowly with water. When lithium comes into contact with water, it forms lithium hydroxide and hydrogen gas. Due to lithium's smaller size and lower reactivity compared to other alkali metals, the reaction occurs at a slower rate.
What colour flame does lithium produce when added to water?
When lithium is added to water, it produces a red flame. This is due to the release of energy as the lithium reacts with the water to form lithium hydroxide and hydrogen gas.
What color does an alkali turn in a flame?
it depends on what is in the alkali, sodium, calcium, lithium all turn different colours, I believe lithium turns purple, an alkali is a compound with hydroxide ie sodium hydroxide is NaOH
What alkali metal produces violet flame when mixed with water?
Lithium is the alkali metal that produces a violet flame when mixed with water. This color arises due to the excitation of electrons in the lithium atoms, leading to the emission of light in the violet part of the spectrum.
What is Chemical identification test of lithium carbonate?
One common chemical identification test for lithium carbonate is the flame test. When lithium carbonate is heated in a flame, it produces a characteristic crimson red color. This color is distinctive for lithium ions and can be used to confirm the presence of lithium in a sample.
Which group of s block elements show distinctive colors when they interact with fire?
Alkali metals, such as lithium, sodium, and potassium, are s block elements that display distinctive colors when they interact with fire. For example, lithium burns with a bright red flame, sodium produces a yellow flame, and potassium results in a lilac-hued flame.
Metal that bursts into flame when it reacts with water?
Potassium is the only metal (alkali metal) where a flame is present. Lithium and sodium fizz but there is no flame. Caesium, francium and rubidium all explode on contact with water.
What colours do potassium chloride sodium chloride and lithium chloride go in a flame?
Color is determined by the respective cation: Potassium - lilac Sodium - yellow Lithium - red
What color is lithium's flame?
Lithium's flame color is primarily a bright red or orange.
What is lithium's flame color?
The color of lithium in the flame test is red.
What is the color of the flame of burning lithium?
The flame of burning lithium is a bright crimson or red color.
What is the color of lithium flame?
The flame of lithium is a bright crimson, or reddish-orange, color.
What colour flame does lithium produce when it is burnt?
Lithium produces a bright crimson red flame when it is burnt.
What is the color of the lithium flame in water?
The color of the lithium flame in water is red. When lithium metal is placed in water, it reacts vigorously to form lithium hydroxide and releases hydrogen gas, resulting in a red flame.
