How do you think about the answers? Very, very slowly. it is a weaker reducing agent than hydrogen. By signing up, you'll get thousands of step-by-step solutions to your homework questions. However, the reaction soon stops because the magnesium hydroxide formed is almost insoluble in water and forms a barrier on the magnesium preventing further reaction. You can sign in to vote the answer. Task 1 . What behavior toward cold water would you predict for strontium and barium? However, some unreactive metals like gold will not react with water in any state. However, iron reacts with steam. Open Yenka file Model 1. Turn on the hot plate and the bunsen burner. Write equations to represent any predicted reactions. 1 decade ago. If the hot water tanks are made of steel (an alloy of iron), then iron would react vigorously with the steam formed from hot water. Magnesium metal does however react with steam to give magnesium oxide (MgO) (or magnesium hydroxide, Mg(OH) 2, with excess steam) and hydrogen gas (H 2). Copper does not react with cold water, hot water or steam. magnesium will not react with cold water. Answer to: Does magnesium react with cold water? Magnesium, being an alkaline earth rare earth (s-block) metal, reacts with water more actively than most other transition (d-block) metals such as iron, copper, zinc, etc do. but it will react with steam. I am confused because in some books it it written it does not react whereas at some websites it is written it reacts with cold water !!! 0 0. mark31167. Magnesium does not react with water to any significant extent. So plz give me right answer and elaborate it too why it does or why it does not? 0 0. Does magnesium react with cold water?? Observe the magnesium and wait until a reaction occurs before adding the gas syringe. … 1 decade ago. Why does magnesium react mildly with cold water but vigorously with hot water or steam producing magnesium hydroxide and hydrogen? Not all metals will react with cold water; some metals that will not react with cold water will react with steam. Ask for details ; Follow Report 23.08.2016 Log in … This is in contrast with calcium, immediately below magnesium in the periodic table, which does react slowly with cold water. Magnesium reacts slowly in water but reacts vigorously with steam. Calcium metal reacts with cold water as follows: Ca + 2 H 2 O → Ca ( OH ) 2 + H 2 Magnesium metal does not react with cold water. Sign in. View Answer. reb1240. Lv 7. magnesium can react with water to produce hydrogen which could cause an explosion, proper care must be used. After several minutes, some bubbles of hydrogen form on its surface, and the coil of magnesium ribbon usually floats to the surface. Very clean magnesium ribbon has a very slight reaction with cold water. Model 1. The reason why Magnesium doesn't really react with cold water is that it becomes coated with Magnesium hydroxide which is insoluble, so it prevents water coming into contact with Magnesium.
