What happens when sodium reacts with cold water?

WebApr 7, 2024 · 1)Sodium is a very reactive metal,therefore sodium metal react violently even with cold water. 2)Magnesium is less reactive metal so it react slowly with cold water,it reacts rapidly only with hot boiling water. 3)The metals like zinc,iron are less reactive which react slowly even with steam. 4)The metals like copper,silver and gold are so un ... WebJun 6, 2024 · If you use ice cold water, very minute amount of hypofluorous acid ( H O F) is also formed which is present in solution in equilibrium. F X 2 + H X 2 O ⇄ H F O + H F Reaction between fluorine and water to form hypofluorous acid and hydrogen fluoride. The reaction proceeds at a temperature of -40 ° C. The alkaline earth metals (Be, Mg, Ca, Sr, Ba, and Ra) are the second most reactive metals in the periodic table, and, like the Group 1 metals, have increasing reactivity in the higher periods. Beryllium (Be) is the only alkaline earth metal that does not react with water or steam, even if the metal is heated red hot. Additionally, beryllium has a resistant outer oxide layer that lowers its r… crystal saint t shirts
