AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
The product formed when zinc reacts with sodium hydroxide is sodium zincate (Na₂ZnO₂).
Zinc is an amphoteric metal, so it reacts with both acids and bases. With NaOH, it forms sodium zincate and hydrogen gas: Zn + 2NaOH → Na₂ZnO₂ + H₂↑. Examiners expect the name sodium zincate; mentioning hydrogen gas as the other product can earn full credit in some mark schemes.
