Magnesium. I believe Magnesium does not react to fresh water but salt water is very corrosive and will disolve the metal.
For example uranium react with oxygen but not with water.
when metals react with water they form hydroxides
Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.
Zinc is a grey metal that can react with water, although it does so slowly. When zinc reacts with water, it produces zinc hydroxide and hydrogen gas.
Iron and Zinc
Carbon dioxide reacts with fresh water to form carbonic acid, which can lower the pH of the water and make it more acidic. In contrast, in salt water (ocean water), carbon dioxide reacts with the saltwater to form bicarbonate ions, which can act as a buffer and help to maintain the pH of the water.
The metal reacts with water to form hydrogen Gas, the vigorous reaction causes the hydrogen to set fire; but WHY they react , is clearly to do with Ionic bonding, Metal+Non metals,
Sodium ion exist in water as the product of a dissociation; sodium (metal) react violently with water
When a metal oxide reacts with water, it forms a metal hydroxide. This reaction typically involves the metal oxide releasing hydroxide ions when it reacts with water molecules. Metal hydroxides are basic compounds that can dissociate in water to form metal cations and hydroxide anions.
It forms NaOH... And its reacts with explosion. .depends on quantity of Na
Metals that react well with water: Sodium - fizzes Potassium - burns Caesium - explodes Metals that react well with acids: Magnesium
When a metal reacts with water, hydrogen gas is produced. This reaction typically occurs when a reactive metal, such as sodium or potassium, reacts with water to form the metal hydroxide and release hydrogen gas.
