An alkali metal (such as Li, Na, K) reacts with cold water violently and exothermically to produce the alkali metal hydroxide and hydrogen gas. The heat produced from the reaction is sufficient to ignite the hydrogen gas, resulting in a flame around the metal.

yes an alkali metal reacts in water as a transition metal does not

any pure alkali metal (such as sodium)

there are some alkali metals. It can be sodium or potassium.

Lithium (Li) is the alkali metal that reacts most slowly with water. It is the first alkali metal and thus, the least reactive of the group. The lithium metal is seen to dart around the surface of the water with some whzzing and effervescence of hydrogen gas. The heat produced from the reaction may not be sufficient to ignite the hydrogen gas, resulting in no flame, compared to other metals like sodium and potassium where the reaction would be more violet and the metal would quickly catch fire.

metal oxides do not react with water .Metal reacts with water and it made metal oxides.

It reacts explosively and is an extremely dangerous alkali metal!

A corresponding metal salt and water are produced.

I believe that you think to alkali metals (ex. sodium).

Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.

The alkali metal essentially replaces one of the hydrogen atoms in a water molecule, producing hydrogen gas and the corresponding metal hydroxide. Depending on the specific metal the reaction can range from vigorous fizzing as with lithium to a violent explosion as with cesium. Often the heat produced by the reaction is enough to ignite the hydrogen as it is emitted.

Sodium chloride is dissociated in water in Na+ and Cl-. Sodium is an alkali metal.

A salt and usually some other substance, most often water, is produced.

Potassium and dont try it at home it is dangerous

the alkali metals bases reacts with the acids to form salt and water example NaOH+HCl=H2O+NaCl

Improve Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water

When an acid reacts with an alkali, it forms a salt along with water. For example, when hydrochloric acid reacts with sodium hyroxide(an alkali), it forms sodium chloride(common table salt) & water.

It is not an alkali metal, but it is alkaline. The carbonate ion is a weak base; it reacts with water in small amounts to form bicarbonate ions and hydroxide ions.

Acid reacts with base to give water and respected salt only.

It reacts strongly in water and bursts into flames when exposed to air. =] and it is the third most reactive alkali metal

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.

Slaked lime is produced when quicklime reacts with water.
