Generally alkaline metals (Group 1) such as lithium, sodium and potassium react with water and at the same time dissolve in it. During the reaction these alakaline metals form alkali solutions (litium hydroxide, sodium hydroxide) and releasing hydrogen gas. Apart from this calcium (belong to Group 2) too able to react and dissolve in water.
A metal oxide reacts with water to produce a metal hydroxide.
The metal that reacts slowly with cold water to form a hydroxide is magnesium. When magnesium reacts with water, it forms magnesium hydroxide and hydrogen gas.
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.
When an acid reacts with a metal hydroxide, it forms a salt and water. This type of reaction is known as a neutralization reaction.
Sodium is a metal that reacts violently with water, sometimes bursting into flames. The reaction produces sodium hydroxide and hydrogen gas.
When a metal reacts with water, it can produce metal hydroxide and hydrogen gas. The metal hydroxide is a basic compound that dissolves in water to form a basic solution, while the hydrogen gas is released as a byproduct of the reaction.
A metal oxide reacts with water to produce a metal hydroxide.
calcium metal dissolves in water because as it gets put in the water, the calcium quickly bonds with the oxygen atom in H2O. so it leaves that with hydrogen, therefore, hydrogen is produced when calcium dissolves in water
Sodium reacts violently with water, while sodium chloride (or table salt) dissolves in water.
The metal that reacts slowly with cold water to form a hydroxide is magnesium. When magnesium reacts with water, it forms magnesium hydroxide and hydrogen gas.
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
potassium in the banana reacts to water and melts the banana
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.
When an acid reacts with a metal hydroxide, it forms a salt and water. This type of reaction is known as a neutralization reaction.
Lead is a moderately active metal. It dissolves slowly in water and in most cold acids. It reacts more rapidly with hot acids. It does not react with oxygen in the air readily and does not burn.
