Water is composed of two hydrogen atoms and an oxygen atom. It exhibits polarity and is naturally found in the liquid, solid, and also vapor states. Its polarity provides it a great solvent and also is generally known together the universal solvent. Because of its variety on earth, that is vital to keep in mind that that is involved in countless gaianation.netical reactions. Plenty of of these gaianation.netical reactions behave in fads that deserve to be categorized making use of the periodic table.
You are watching: Which alkaline earth metal will not react with liquid water or with steam?
Group 1: Alkali Metals
A typical characteristic of most Alkali steels is their capability to displace H2(g) from water. This is stood for by your large, negative electrode potentials. In this event, the group 1 metal is oxidized to its metal ion and also water is reduced to form hydrogen gas and also hydroxide ions. The basic reaction of one alkali steel (M) with H2O (l) is given in the following equation:
From this reaction the is evident that OH- is produced, creating a an easy or alkaline environment. Team 1 facets are called alkali metals since of their capability to displace H2(g) native water and also create a basic solution.
Alkali metals are likewise known to react violently and also explosively through water. This is since enough heat is offered off during the exothermic reaction come ignite the H2(g).
Alkali metal Hydrides and Water
Similarly come the group 1 oxides, the hydrides of the group 1 elements react through water to type a basic solution. In this case, however, hydrogen gas is created with the steel hydroxide. The general reaction for alkali steel hydrides and water is given below:
This reaction can be generalised to all alkali steel hydrides.
Group 2: Alkaline earth Metals
The majority of Alkaline earth Metals also produce hydroxides when reacted through water. The hydroxides of calcium, strontium, and also barium are just slightly dissolve in water; however, enough hydroxide ions are created to do a straightforward environment. The general reaction that calcium, strontium, and also barium with water is stood for below, wherein M to represent calcium, strontium, or barium:
Magnesium (Mg) reacts through water vapor to form magnesium hydroxide and also hydrogen gas. Beryllium (Be) is the just alkaline earth metal that does not react v water. This is because of its little size and high ionization power in relationship to the other facets in the group.
Alkaline earth Metal Oxides and Water
Similarly to the alkali steel oxides, alkaline earth metal monoxides incorporate with water to kind metal hydroxide salts (as illustrated in the equation below). The exception to this general assumption is beryllium, whose oxide (BeO) does no react v water.
One the the most acquainted alkaline planet metal oxides is CaO or quicklime. This problem is regularly used to treat water and to remove harmful (SO_2(g)) from industrial smokestacks.
Group 14: Carbon Family
For the many part, team 14 elements do not react with water. One interesting consequence of this is the tin (Sn) is often sprayed as a protective great on iron can be ~ to protect against the have the right to from corroding.
