Step 1
Step 2
Evaluate the reaction with sodium hydroxide
Answer
-
Al₂O₃ (Aluminum oxide): Reacts with sodium hydroxide to form sodium aluminate, which is a salt.
-
P₂O₁₀ (Phosphorus pentoxide): Reacts with sodium hydroxide to form sodium phosphate, which is a salt.
-
SO₂ (Sulfur dioxide): Reacts with sodium hydroxide to form sodium sulfite, which is a salt.
-
SiO₂ (Silicon dioxide): Does not react with sodium hydroxide to form a salt.
