Sodium Reacting with Water
Numéro d’image : 12003153
| Sodium reacting with water. The sodium metal (Na) is the small ball at center. The acid-base indicator phenolphthalein has been added to the water bath. This shows the production of sodium hydroxide (NaOH) by the reaction. Phenolphthalein turns purple in alkaline solutions,and sodium hydroxide is a strong alkali. The equation for this reaction is: 2Na + 2H2O ---> 2NaOH + H2. The hydrogen (H2) produced is burnt off by the heat of the reaction. Sodium is a very reactive metal that must be stored under oil as it reacts with both water and atmospheric oxygen | |
