Question

Write the chemical equation for potassium reacting with cold water

Answer 1

Reaction of potassium with cold water:

• Potassium is a highly reactive metal which reacts vigorously with cold water to form Potassium hydroxide and hydrogen gas with the evolution of heat.
• The balanced chemical equation for Potassium reacting with cold water is

$\underset{\left(\mathrm{Pottasium}\right)}{2\mathrm{K}\left(\mathrm{s}\right)}+\underset{(\mathrm{Cold}\mathrm{Water})}{2{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}\to \underset{(\mathrm{Pottasium}\mathrm{Hydroxide})}{2\mathrm{KOH}\left(\mathrm{aq}\right)}+\underset{\left(\mathrm{Hydrogen}\right)}{{\mathrm{H}}_2\left(\mathrm{g}\right)\uparrow }+\mathrm{Heat}$
