Melting point in group 1
WebGroup 1 metals such as potassium, sodium and lithium, react with water to produce a metal hydroxide and hydrogen. For example: lithium + water → lithium hydroxide + hydrogen 2Li (s) + 2H₂O (l) → 2LiOH (aq) + H₂ (g) The observations for the reaction of water with either potassium or sodium or lithium have the following similarities: Web5 apr. 2024 · The lower melting point of the mixture (400–420 °C, or 750–790 °F) compared with that of pure lithium chloride (610 °C, or 1,130 °F) permits lower-temperature operation of the electrolysis.
