Complete the reaction: PbO+2NaOH?


Open in App
Solution

Completing the given reaction:

  • The given equation should follow the law of conservation of mass.
  • Hence, the complete balanced chemical equation can be written as:

PbO(s)Leadoxide+2NaOH(aq)SodiumhydroxideNa2PbO2(s)Sodiumleadoxide+H2O(l)Water

  • The given reaction can be classified as an acid-base reaction, which PbO acts as an acid, and NaOH acts as a base.
  • Here Lead(II) oxide reacts with Sodium hydroxide to produce Lead(II)-sodium oxide and water, which takes place at a temperature near to about 400°C.

hence, the Complete reaction is given as:PbO(s)Leadoxide+2NaOH(aq)SodiumhydroxideNa2PbO2(s)Sodiumleadoxide+H2O(l)Water.
