inorganic chemistry - Why does potassium react more …
Sodium and potassium are excepted from this inhibition because of the great solubility of their hydroxides and the possibility of melting. Lithium may start out moderately fast, but slow down as the pH rises, and overall seem a lot slower than sodium or potassium because it will not melt in water and has a solid surface that becomes inhibited by the high pH after some reaction.
