Question
Can we keep sodium immersed under water? Why?
Advertisements
Solution
No, we cannot keep sodium immersed in water because it reacts vigorously, even with cold water, to form sodium hydroxide, hydrogen gas, and a large amount of heat.
\[\ce{2Na_{(s)} + 2H2O_{(l)} -> 2NaOH_{(aq)} + H2_{(g)} + Heat}\]
