Sodium hydroxide acts on Aluminum oxide to form:
Correct answer: C. NaAlO2
- A. NaAlO3
- B. Na3Al2O6
- C. NaAlO2
- D. NaAl2O3
Explanation
The reaction between sodium hydroxide (NaOH) and aluminum oxide (Al2O3) results in the formation of sodium aluminate (NaAlO2) and water. The chemical equation for this reaction is:2 NaOH + Al2O3 → 2 NaAlO2 + H2OOption C is correct because it represents the correct formula for sodium aluminate. Options A, B, and D are incorrect because they do not accurately reflect the products of this typical reaction.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
