When an alkali metal reacts with water it produces what?
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
Which metal reacts with water and burns with a lilac flame?
Potassium has a violet color in the flame test.
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 is the difference between the colours produced by alkali metals and calcium?
The colors produced by alkali metals are typically vibrant, ranging from lilac (lithium) to deep violet (cesium) when they burn. In contrast, calcium typically produces a more subtle orange-red color when heated, which is not as intense as the colors of alkali metals.
What alkali metal reacts violently in water with a purple flame?
Potassium and dont try it at home it is dangerous

What metal produces a crimson flame?
Strontium is a metal that produces a crimson flame when burned.
What metal burns with bright flame but doesn't react with water?
Magneseum. an Alkali earth metal
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.

Not for sale at Arbee's this alkali is a real go-getter in vacuum tubes and is known for its ruby-colored flame test?
What is cesium? Cesium is a highly reactive alkali metal that is not typically found for sale at Arbee's. It is commonly used in vacuum tubes due to its ability to efficiently emit electrons. When cesium is burned, it produces a distinctive ruby-colored flame, making it easily identifiable in a flame test.
What color flame is produced when potassium metal reacts with water?
When potassium metal reacts with water, it produces a lilac-colored flame. This flame color is a result of the energy released during the chemical reaction between potassium and water.

What alkali metal reacts violently in water with a purple flame?
Potassium and dont try it at home it is dangerous
Is an alkali metal a base?
The metal itself, no. But after reacting with water or something containing water it produces a very strong base.
