5.0 Water and Hydrogen
5.3 Reaction of metals with steam
How does steam react with metals?
Materials and substances required
- Magnesium ribbon
- Sand and water
- Boiling tube, retort stand and Bunsen burners
Open the video below, reaction of magnesium with steam(Courtesy Youtube - Reaction of magnesium with steam by liyauman), make observations then answer Questions 5.3.
Caution: Hydrogen burns explosively when it mixes with air and catches fire. It is therefore collected in small quantities only (in test tube or boiling tube), especially in experiments involving heating.
- State one similarity in products between reaction of metal with water and reaction of metal with steam.
- Identify one difference in products between reaction of metal with steam and reaction of metal with water
- Write word equations for the reaction between
- magnesium and steam
- sodium and steam
- potassium and steam
- calcium and steam
- Write a general equation for the reaction between metal and steam.--
