What is formed when a group 1 metal reacts with water?

Answer 1

The reaction that will occur with water and a metal depends on the valence electron configuration of the metal. Group 1 alkali metals react with water vigorously and sometimes explosively. This reaction produces a metal hydroxide and hydrogen gas. For group to alkaline earth metals, beryllium does not react. Magnesium burns in steam to produce magnesium oxide and hydrogen gas. It also reacts in cold water to form magnesium hydroxide and hydrogen gas. Further down group 2 the metals react increasingly with water to form the metal hydroxide and hydrogen gas. For the most part transition metals do not react with water. Mn (IV) will form MnO2 with water. Vanadium 4+ or 5+ forms VO2+ with water. Cr(VI) reacts with water to from the chromate and dichromate ions.

Answer 2

Usually, the metal replaces the Hydrogen in the H20, so you get a salt or a hydroxide, along with the release of Hydrogen gas [H2].

You've got a lot of similar questions and answers in WikiAnswers. Most of the Answers give Hydrogen as the Answer, with various different mechanism described.

Answer 3

alkaline metals are explosive when expossed to moisure they might even react with moisture in the air.

If you were to drop a half a kilo block of potasium into a barth tub full of water it would go off like a hand grenade.

Im not sure what will be made but I assume hydrogen gas along with some carbon dioxide

Answer 4

When a Group 1 metal reacts with water, it forms a metal hydroxide and hydrogen gas. The metal hydroxide is alkaline in nature and the reaction is highly exothermic, leading to the liberation of hydrogen gas.

Answer 5

With Cold Water = Metal Hydroxide.

With Hot Water = Nothing

An acid is formed when certain metals react with water

Answer 6

With Cold Water= Metal Hydroxide

With Hot Water= Nothing

Answer 7

hydrogen, but the reaction causes the hydrogen to easily catch on fire.
