Why does sodium react vigorously with water?
Answers
Answer:Alkali metals in general are extremely reactive metals. They are highly reducing in nature. Hence, they react with water forming their corresponding hydroxides evolving dihydrogen gas.
In case of sodium - as cited in your question - its reduction potential is −2.7109 V hence it easily reduces hydrogen.
Also, as the density of sodium is quite low it floats on the water. It immediately reacts with water to form a white trail of NaOH which further gets dissolved to give a colourless solution.
This reaction is highly exothermic evolving a lot of heat which is sufficient enough to melt sodium due to its low melting point.
Sodium moves in water as the dihydrogen gas formed below the waterline pushes sodium. If sodium is trapped in the container the increasing temperature could induce dihydrogen to catch fire
Answer:
Because it is highly reactive in nature.
Explanation:
And when it comes in contact with H2O the ions get seprerated and Na+ react with O and H2 vigerously and this type of reaction is called Exothermic reaction. I hope this will clear your doubt.
