How Do Group 2 Elements React With Water?


The Group 2 metals become more reactive towards water as you go down the Group. There is an additional reason for the lack of reactivity of beryllium compared with the rest of the Group. Beryllium has a strong resistant layer of oxide on its surface which lowers its reactivity at ordinary temperatures.



Which metal reacts violently with Coldwater?

Detailed Solution

The correct answer is Potassium. Metals at the top of the reactivity series such as potassium and sodium react violently with cold water.


What metal explodes in water?

sodium


Which metal reacts with water most vigorously?

Sodium metal reacts vigorously with water.


How do group 2 elements react with water?

The Group 2 metals become more reactive towards water as you go down the Group. There is an additional reason for the lack of reactivity of beryllium compared with the rest of the Group. Beryllium has a strong resistant layer of oxide on its surface which lowers its reactivity at ordinary temperatures.


How do metals react with water?

Reactions of metals with water

  1. When a metal reacts with water, a metal hydroxide and hydrogen are formed.
  2. For example:
  3. sodium + water ➞ sodium hydroxide + hydrogen.
  4. calcium + water ➞ calcium hydroxide + hydrogen.
  5. The apparatus below is used to react calcium with water and collect the gas.


Does Iron react with water?

The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur.


Which element is least reactive with water?

Detailed Solution. The correct answer is Option 2, i.e Lithium. All the elements given in the option are alkali metals. Among these lithium is less reactive with the water.


Does copper react with water?

Metals such as lead, copper, silver and gold do not react with water at all.


Is potassium reactive with water?

Potassium reacts with water more slowly than does rubidium, which is placed under potassium in the periodic chart. It reacts with water more rapidly than does sodium, which is placed higher in the periodic chart. Potassium is non-water soluble, but it does react with water as was explained earlier.


Does lithium react with water?

In what way and in what form does lithium react with water? Lithium reacts intensely with water, forming lithium hydroxide and highly flammable hydrogen. The colourless solution is highly alkalic.


Which element has the fastest reaction with water?

The alkali metals (Li, Na, K, Rb, Cs, and Fr) are the most reactive metals in the periodic table - they all react vigorously or even explosively with cold water, resulting in the displacement of hydrogen.


Why do alkali metals react with water?

Alkali metals react with water to produce heat, hydrogen gas, and the corresponding metal hydroxide. The heat produced by this reaction may ignite the hydrogen or the metal itself, resulting in a fire or an explosion.


What elements will react violently with water at room temperature?

Answer. Two metals, named Sodium and Potassium, react vigorously with water at room temperature.


What chemical reacts violently with water?

Common Water-Reactive Chemicals

Chemical NameReaction with Water
Acetyl chlorideViolently decomposes to HCl and acetic acid
Aluminum bromideViolent hydrolysis
Aluminum chlorideViolent decomposition forming HCl gas
Boron tribromideViolent or explosive reaction when water added


What element group react very violently with water?

Group 1 elements


What makes water reactive?

Water reactive chemicals are chemicals that react vigorously with moisture. The most common water sensitive chemicals include sodium, potassium, lithium metals and aluminum alkyls. A list of some water reactive chemicals is at the end of this SOP.


How do group 1 elements react with water?

All the alkali metals react vigorously with cold water. In each reaction, hydrogen gas is given off and the metal hydroxide is produced. The speed and violence of the reaction increases as you go down the group. This shows that the reactivity of the alkali metals increases as you go down Group 1.
