Every metal except precious metals like gold and silver reacts with water. "We'd like to predict the specific reactions of metals and combinations of metals with water and what the products of those reactions are, by computational methods first as opposed to determining them experimentally," Kesz...
When sodium metal reacts with water, the resulting heat melts the metal almost immediately into a grey-silver ball. The hydrogen gas evolved during this reaction propels the ball rapidly across the surface of the water, leaving a white trail of sodium hydroxide that eventually dissolves into a ...
K Melts to form a silvery ball, which moves about very quickly on the water surface with a hissing sound, and it burns with a lilac flame. Na Sodium reacts with cold water in a similar way as potassium, but less vigorously. Burns with a golden yellow flame. Ca Sinks to the bottom. ...

Alkali metals can react explosively with water and it is textbook knowledge that this vigorous behaviour results from heat release, steam formation and ignition of the hydrogen gas that is produced. Here we suggest that the initial process enabling the a
Text SolutionVerified by Experts Because active metals react with water. Moreover, the hydrogen ion of water gets reduced to hydrogen gas before the cations of active metals can be reduced by passing electric current. Show More | ShareSaveClass...
(ii) Potassium metal reacts with water to give potassium hydroxide solution and hydrogen gas is evolved in the reaction. (iii) Solid potassium chlorate upon heating forms potassium chloride and liberates oxygen gas. (iv) An aqueous solution of aluminium chloride reacts with an aqueous solution ...
Metals from potassium to calcium are highly reactive and even react with water. While metals from magnesium to lead can react with acids. Metals from copper to platinum are highly unreactive and don’t react with any other substance in normal conditions. This is the reason why platinum and go...
To prevent reaction with air, very reactive metals (K, Na) are stored underparaffin oil, and quite reactive metals (Ca) are kept inairtight containers. Gold is the least reactive of all metals - it does not react with oxygen and water, so it needs no special method of storage. ...
