reaction of metals with water class 10

Metals show displacement reactions on the basis of their reactivity series. Therefore, the reactivity series of metals can be used to predict the reactions between metals and water. 2NaOH + Zn ⇨ Na 2 ZnO 2 + H 2. Reaction Between Metals and Acids Iron forms rust (iron oxide) when reacts with moisture present in atmosphere. Ca (s) + 2H 2 O(l) à Ca(OH) 2 (aq) + H 2 (g) Whereas metals like aluminium, iron and zinc reacts neither with cold nor hot water. Your email address will not be published.

When steam is passed over magnesium metal, magnesium oxide and hydrogen gas are formed. Question 1. Filed Under: Class 10 , Metals and Non-metals Tagged With: reaction of metals with water However, alkali metals react vigorously with water. The reaction of calcium with water evolves heat that is not sufficient for the hydrogen to catch fire. The metal which does not react with water even on strong heating is copper. Example: Sodium hydroxide gives hydrogen gas and sodium zincate when reacts with zinc metal. Reaction of aluminium metal with water: Reaction of aluminium metal with cold water is too slow to come into notice. Reaction of magnesium metal with water: Magnesium metal reacts with water slowly and forms magnesium hydroxide and hydrogen gas. Reaction of Base with Metals: When alkali (base) reacts with metal, it produces salt and hydrogen gas.        cold, 2Na + 2H2O ———-> 2NaOH + H2 +heat also been provided for your reference.
