Excess of NaOH reacts with Zn to form:
Show Hint
- \( \text{ZnOH}_2 \)
- \( \text{NaZnOH}_3 \)
- \( \text{ZnO}_2 \)
- \( \text{Zn(OH)}_2 \)
The Correct Option is D
Solution and Explanation
Step 2: Conclusion. Thus, the correct answer is \( \text{Zn(OH)}_2 \).
Top Questions on p -Block Elements
Given below are two statements:
Statement I: Nitrogen forms oxides with +1 to +5 oxidation states due to the formation of $\mathrm{p} \pi-\mathrm{p} \pi$ bond with oxygen.
Statement II: Nitrogen does not form halides with +5 oxidation state due to the absence of d-orbital in it.
