Alkali metals, for example: 2Me + 2H2O = 2MeOH + H2 Me is the metal
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
violent reaction happens
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
The products of the reaction between alkali metals and water are a hydroxide and hydrogen:2 Na + 2 H2O = 2 NaOH + H2
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.
because they produce(form)an alkali when they react with water.
alkali metals react violently in cold water
Yes, reacting with water alkali metals form alkaline solutions (alkali metals hydroxides dissolved in water).
Alkali metals and alkali earth metals react with water; the other metals doesn't react.
Acid + alkali ---> Salt + Water for exampleSodium Hydroxide + Hydrochloric Acid ---> Sodium Chloride + Water
Alkali metals and alkali earth metals react with water; the other metals doesn't react.
Hydrogen can by generated, for example, from the reaction between alkali metals and water.
When alkali metals react with water they produce an alkali (basic) solution. No because they form basic oxides and they neutralise acids
This is the generic reaction where "M" could represent any of the alkali metals.2M + 2H2O --> 2MOH + H2This really does not help anybody... at all. I asked for the metal not the formula
The general reaction is:2 Me + 2 H2O = 2 MeOH + H2where Me is an alkali metal.Very probable francium react violent with water.
Alkali Metals = XWater = H2O (duh. lol)Hydroxide ion = OH2X(s) + 2H2O(l) ------> 2XOH(aq) + H2(g)If you need a example here's one:e.g Lithium and Water2Li(s) + 2H2O(l) -----> 2LOH(aq) + H2(g)Oh sorry.... "WORD EQUATION" didn't see....Alkali Metals + water ------> Alkali metal Hydroxide + Hydrogen gase.g Lithium + Water ------> Lithium Hydroxide + Hydrogen gas
the answer for the reaction HNO3 AND NaOH is :- NaNo3 + H20 that coz when acid reacts with a metal oxide it produces salt and water --> all metals are alkali so if acid reacts with either metaloxide or alkali it produces salt and water... hope that helped.. ;)
For example hydroxides of alkali metals are very soluble in water.
Group 1 elements are known as alkali metals because they react with water to form alkali (or bases).
In order of reaction strength: Lithium Sodium Potassium Rubidium Cesium Francium Look in related links for a video demonstrating the reactions of different alkali metals mixed with water.
