Question
Reaction of Zn(OH)2 with NaOH produces:
Answer: A
💡 Solution & Explanation
Step 1: Zinc hydroxide, Zn(OH)2, is an amphoteric hydroxide that reacts with strong acids as well as strong bases. Step 2: When reacted with sodium hydroxide (NaOH), it dissolves to form a soluble salt called sodium zincate: Zn(OH)2 + 2NaOH -> Na2ZnO2 + 2H2O. Step 3: Thus, the compound produced is Na2ZnO2, matching option (a).
