When 2 mL of sodium hydroxide solution is added to few pieces of granulated zinc in a test tube and then warmed, the reaction that occurs can be written in the form of a balanced chemical equation as :
  1. NaOH + Zn → NaZnO2 + H2O
  2. 2NaOH + Zn → Na2ZnO2 + H2
  3. 2NaOH + Zn → NaZnO2 + H2
  4. 2NaOH + Zn → Na2ZnO2 + H2O

Solution

2 NaOH + Zn → Na2ZnO2 + H2
