Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water
Example: ================
Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2
Improve Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water
Alkali metals, for example: 2Me + 2H2O = 2MeOH + H2 Me is the metal
violent reaction happens
Alkali metals are famous for their vigorous reactions with water, and these reactions become increasingly violent as one moves down the group. The Reaction of Alklali metals as folow: Alkali metal + water → Alkali metal hydroxide + hydrogen gas
1) Alkali metals are stored in oil to minimise reaction with oxygen or water, it's a physical barrier towards air but the alkali metals still gradually corrode a traces of oxygen and water diffuse through. The reaction of alkali metals with water gets more violent for elements lower in the group e.g. (Li < Na < K < Rb < Cs). Adding them to water will cause an explosion due to the extremely exothermic nature of reaction, and can be rather dangerous and some alkali metals can react violently with just moisture in the air. Most of the alkali metals float on the top of the water, depending on how big the alkali metal is determines the size of the reaction this is because they're less dense that water itself and also during the reaction the alkali metals give of hydrogen gas which is quite flammable. Alkali Metal + Water » Metallic Hydroxide + Hydrogen The francium would be like any other alkali metal, it would be very violent like the other alkali metals.
as you go down there are more electrons on the outer shells which makes them more reactive when in contact with water
Acid + alkali ---> Salt + Water for exampleSodium Hydroxide + Hydrochloric Acid ---> Sodium Chloride + Water
A strong reaction with the formation of a hydroxide - MeOH.
For example the reaction with water.
The reaction of alkali metals with water release hydrogen.
The reaction of alkali metals with water release hydrogen.
The products of the reaction between alkali metals and water are a hydroxide and hydrogen:2 Na + 2 H2O = 2 NaOH + H2
