Step 1
Which of the following compounds will neutralise sulfuric acid?
Answer
To determine which compound neutralises sulfuric acid, we should consider the nature of sulfuric acid as a strong acid. A strong base is needed for neutralization. Among the given options:
-
A sodium chloride: This is a salt and does not neutralize acids.
-
B sodium hydroxide: This is a strong base, which can effectively neutralize sulfuric acid, forming sodium sulfate and water:
ightarrow ext{Na}_2 ext{SO}_4 + 2 ext{H}_2 ext{O}$$
- C sodium nitrate: This is also a salt, which does not neutralize sulfuric acid.
- D sodium sulfate: This is the salt formed after neutralization and cannot neutralize sulfuric acid itself.
Thus, the correct answer is B sodium hydroxide.
